MX946

Almost done!

Ive been reading posts on here for quite a while now. Ive heard the name Zippy quite often. How does it work for a tune? I was under the impression you had to bring it to someone with a dyno and they basically run it, and adjust the computer accordingly? I also heard of someone "sending you a tune". Im assuming on a flash drive or programmer or something? Never done this before....

Good advice ill take it. So far the engine was broke in at the machine shop. Right now since its not tuned but starts up, wont really idle, im thinking its just running on the stock computer so the paint guy can move it around the shop. It sounds like theres quite a bit of work that needs to be done before I can really drive it. Ill tow it somewhere else... anyone from Denver that knows the best place you could take this to get it finished up? Any opinions on AWD vs 2wd on a higher hp truck if you had the choice?

Hahaha thanks for the replies everyone! Im excited to get this thing back. I agree with you bad2k I wish it was 100% ready when I pick it up from paint. The painter is doing black with a hint of pearl cherry, should be bad ass. The guy doing the work is going through some personal issues that are obviously not my problem. Im paying about 23,000 for all this work which also includes a few things I didn't mention like lowering, dyno mat, new front end basically, other misc. small things. I didn't think it was a bad price but maybe someone could give me some feedback on that as well. Another thing he mentioned that started worry me was him telling me originally that he would install a switch to convert the truck from awd to 2wd on the fly. He claimed I would be able to launch in AWD and then hit the switch and go into 2 wheel drive. I did a little research online and seems that's not possible. Any experience with that? Also, he claims I will be putting down approx. 550 whp. That seemed a little high to me for being n/a. The true test will be on the dyno next week and I will gladly post results. Should I or do you think I will need to rebuild my rear end? Or transmission to handle the power? Thanks again for the feedback guys, appreciate it

I purchased a 2003 Silverado SS about 4 1/2 months ago. I immediately brought it to a friend of a friend that has a shop in Denver doing misc. custom work on trucks. We started out just doing heads exhaust, tune and paint. We ended up going quite a bit further with the build. Here is a short list of the mods that have been done. You will have to forgive me for my lack of knowledge on the parts installed. I am not a mechanic just a guy that loves fast trucks. Im hoping to get some feedback on what these items would normally cost and what I can do to make sure he installed the right parts and did a good job. Its been 4 1/2 months hes had the truck and its just now in for paint. I stopped by the paint shop and got to start it up. It sounded good, but still needs to be tuned. The main reason for my concerns and lack of trust with the mechanic is because ive recently caught him lying to me about miscellaneous items and now im questioning everything.
