[Do I Have A Tune?]

Perfect, thanks!

[Do I Have A Tune?]

I bought this Vmax last year, repo deal. The throttle/power is very touchy when taking off from a dead stop when driving normal, this beotch wants to go... (yeah I know, I drive normal sometimes). It took some getting use to... I drive my friends 5.3, its a dog with the same peddle movement, (no he won't race me) .

 

It almost seems I have a tune or something, how would I tell?

You should probably still get a new cam!

Ha, you got that right! Don't think it hasnt crossed my mind... Its already a tire smoker... I had to sell my Camaro because I kept getting in trouble..

That's great news, i would blame the oil filter for that, what filter brand did you use before the Mobil 1?

 

I'm not sure what filter was on there, I had just purchased the truck( I had it just a few months). The filter may have restricted the oil a little too much huh? Well so far is has been fine and on the 2nd oil change of the Mobil One. Going to put the 6.0 to the test tomorrow. Hauling the atv's to the Cali sand dunes from Dallas, about a 3000 mile round trip.

Update, I changed the oil to Mobil One and Mobil One filter and the seemingly lifter ticks at startup went away. Just thought I would share that.

[Which Make/Model Master Cylinder. Help! :-)]

You can do a vin decode yourself. Google it.

That said, I know the NBS GM trucks (with AFM) have a problem with failing lifters.

 

But a V-Max doesn't have that feature, correct??

I do believe mine has the afm. Switching to V4?

Is this a NBS 2007 or a 2007 "Classic"??

 

Totally different body styles entirely...

 

NBS- 6.0L V-Max

I will try to get a video. Its so seldom it will be difficult. Piston slap? That sounds like an engine death sentence... Although it sounds like a lifter/ rocker tick to me, but I'm far from an expert.

[Big Hello From Dallas!]

I dumped my diesel recently and got this 1500 with some balls. As soon as I get some research done, it won't be stock for long. I've been wanting a tire burner for a long time. I'll get some pics up soon.

[Pulling Stuff With The Ss]

I'll be towing a fair amount with mine, 3000 - 6000lbs. My trailer brake controler finally showed up today. I've only towed 3000lbs so far and as long as there wasn't a nasty head wind I couldn't tell it was back there.

[Is It Time For A Cam Upgrade?]

When I start my truck sometimes I here a lifter being a little lazy for a bit, it ticks for 15-20 seconds. So it sounds like it needs new lifters. If I do that I should go ahead and have a cam put in.

 

Is there a shop in the Dallas area that can do that for me? I don't think I want a dealership doing that for me.
