  1. As above, never heard of this coating before. I would also cut the filter open and check it for any metallic debris.

    What have you done to your truck? Does it have cats? If so it's common for them to plug up around that mileage, and that would or could be the cause. Also what octane of fuel are you running? Premium fuel only.

    You can also pull the plugs, and check them, as well as bad plug wires, or a loose or broken plug.

    These engines are known to have a piston slap issue, and that could be the coating that the guy was talking about that is put on at the factory on the skirts.

    Give us a rundown of your mods if you have any, and I'm sure it's going to be easier and cheaper than you think.

    Bad or lower octane fuel will cause knocking under acceleration, broken valve spring is more noticeable under acceleration, but can also hear at idle, plugs and wires can also be the cause but you would more then likely get a misfire code, Cats are a culprit of many noises and can come out of the blue leaving you scratching your head.

    Let us know what is done to it and we'll be able to steer you a little better

    It could also be a lifter issue, such as one not pumping up/clogged or a collapsed lifter causing noise in the valve train. I've seen them make noise before if the truck has not had regular oil changes. Here's a video on what I am talking about. Not saying the fix the guy does in the video is what you need just an example of a possible noise you could be hearing.

  2. Hard water ?

    Exactly my first thought as well. I've washed my truck off with our well water that is not softened and it water spotted so quickly it was impossible to get it dried off without tons of spots. Now it always gets washed with the softened water. I also agree to seal it after you clay bar it with some good wax, definitely makes a big difference for the next wash.

  3. A pulley change is a world of difference going from 4-5lbs to 9-9.5lbs of boost LOL... What you really need that will put a huge smile on your face and get that pig out of the whole is a nice 3000-3200 stall... It will be night and day difference and you would never regret it....

    Like you said the pulley change really wakes it up. I would swap to a different stall other than stock but for what I currently use the truck for I think I will leave it alone. It still pulls really well, especially with the boost kicking in down low in the RPM's, seems to get into boost right around 2500 if I recall.

  4. Nice runs matt, she sounds awesome.

    Thanks! It pulls a lot better now with the 2.8 pulley, never did make it back to the track to see what it could do after the pulley swap, I've just been way to busy. I think the tune needs some adjustments after the pulley swap, other than that it runs excellent!

  5. You will get use to it. As long as you can read your wide band. The boost doesn't matter so much. I had gauges on my pillar, I ended up taking them off and swapping to the SoCal overhead gauges because every Tom dick and Harry wants to race. Lol!

    Good call, you are totally right. The wideband is the closest gauge to me and pretty easy to see, so like you said that is all that matters. I'm glad I now don't have to think I need to spend any money on the truck lol!

  6. Talked to Zippy yesterday and it looks like the 3.2 pulley with the underdriven rear pulleys is only making something like 3-4 psi, thus the slow time. So I swapped on a 2.8 pulley and went for a romp around the block and immediately noticed a huge difference in power and boost. Glancing at the gauge it looks like its around 7-8 psi +/-. I need a pillar pod with a digital boost gauge as its hard to see the overhead console gauges while smashing on it.

  7. Nice run! How much boost are you running?

    Thanks, I think it is around 5-6 psi but I did not pay to much attention to my overhead gauge pod during my runs, where the boost gauge is. I really want to get a nice pillar pod setup as the overhead gauges are hard to see. I'll post up the video link in a bit, it's being slow to upload.

  8. I finally made it out to the track for the test and tune well yesterday (Weds 7/16). I made 3 passes with the truck and it ran pretty good, my main problem was heat soak my best run was 14.68 at 91.80 with a 2.21 60 ft. This was with a IAT of 145F so it was definitely hot, outside temp was 70-75f. I think it could run faster, but I'm sure my stock muffler and exhaust manifolds along with high IATs where limiting my times. I sent Zippy the logs maybe there could be some tweaks but I'm guessing that's about all shes got for now.... Anyways I'm happy with the outcome and it was a blast. I've got video just need to edit them and upload I'll try and get them up sometime soon.

  9. This is the first time I really read the whole build post and then watched the video. Truck looks very nice and is in excellent shape considering where you live. Shouldn't take much more tuning and it'll be a hell of a runner. One thing you have with that unit is that even though it is the old technology there is plenty available to improve it. Supersub now makes a phenolic spacer for them, rear pulley upgrade kit, front pulley upgrade kit, and has in the past made a 102mm throttle body upgrade for it. All 4 are items that make the blower more efficient, cooler, and reliable. The spacer keeps the heat down and efficiency up. The rear pulley kit allows you to spin the blower faster without having to have a smaller front pulley. A small front pulley tends to bring pulley slip so changing the rears lets you keep the larger front pulley and still make more boost. The larger throttle body swap also brings the boost up without changing any pulley at all effectively making it more efficient. Last but not least if I recall he makes a kit to install the newer 4 bolt pulley up front which allows for a pulley change without having to press the pulley on and off. You simply take the belt off, pull the 4 bolts out, and swap the pulley. Not trying to be a sales person for him, just making you aware of options to bring more fun into it.

     

    Hey Zippy, thanks for the comments! I just got back from driving the truck all weekend as usual out to the lake and back, its been running really good thanks to your excellent tuning. I will keep those upgrades in mind for the future, right now I'm just going to keep it pretty stock to keep from blowing anything up on this truck, I do however have the 4 bolt pulley upgrade on the front so the pulleys can easily be swapped, I have the 3.2 on it right now and notice no slip at all, I also have a 2.8 but like you said swapping the rears is the best. The rear pulleys used to be over driven but I swapped them back to the stock setup to keep the boost at a low level. If I had some extra cash laying around I would definitely look into the spacer but it seems alright for the moment.

     

    I'm going to take it out to the test and tune on Wednesday of this week, should I run the scanner on it when I do some passes?

  10. Great video Matt! I bet its much more fun to drive! 6psi ain't bad for starters. Pulley to 10psi and get a set of 80s :lol:

    Sounds great too! Love that blower whine. Hopefully I'll be able to cruise the highwys of anchorage here before too long.

    Thanks Brandon! I do have a 2.8 front pulley.... lol but that's probably just a good way to break stuff on my worn out truck hahaha

     

    I'll have to run this out by the track sometime when a test and tune is going on and see what it will do over a stock SS time.

  11. Looks awesome, Matt! Lol, seeing you just slap that thing on there without any farting around just makes my itch to do the same even worse!

    Thanks! It was definetly a quick install, pretty much one a days work.

     

    In other news I drove the truck about 200 miles this weekend out to Big Lake and back, seems to run really good. My wideband died but it turned out to be a wiring issue so I fixed that for the return trip. I also think the tune still needs some tweaks to get it just right as I didn't get into boost much at all except for a couple times and it seems to be sucking gas down quick! Guesstimating like 10 mpg highway? I'm imagining that it should still get decent-ish mileage for highway driving and obviously city will be down from stock. No complaints about the tune at all though, Zippy is doing an AMAZING job as usual, super quick response he's onto the 7th revision and it runs sweet. I'll get a video soon!

    When it does get into boost it seemed to be running about 10.9-11.5 afr which I would imagine is perfect, Justin had me scared when he mentioned anything above 11.8 in boost is bad news!

  12. Yes sir! Car trailer is to get the SS to the track. And, that is my wife's pickup, with a 6.2 in it. That thing is awesome. I think it is probably just as fast or faster than her TBSS.

    Isn't that a pretty rare option to have the 6.2L in a regular Silverado or did you put it in there?
