I havent been on in quite some time, I see anything on ATI (procharger) I feel I need to chine in... I hope you dont give up on the car stick it in the corner for a week and forget about it.. sometimes it needs to be done.
Your getting alot of great advice on this Tom has some greas input as well as Jody, I have literally sold and installed hundreads of these units more in the marine field but also in automotive as well and just about any internal combustion engine i could mess with.
http://profile.myspace.com/index.cfm...endid=68611071 I have alot of pics on there you can look at. I also did some R&D for Dan Jones when he started the company for a number of years and its a great product you just need to cover some basics. All the input your getting is great I wont knock any just tell you some basics to fallow on a carb deal.
1 Boost read it after vacume.
2 Fuel boost reference before vacume make sure your at 1 extra pound fuel for every pound of boost.
3 Timing dont go too low you will hurt it worse. I like to lock out on 29 total I do not take timing out under 28 under psi your engine should be just fine.
4 Make sure your belt is tight VERY TIGHT Comon Problem!
5 Remember it takes power to turn your head unit low boost might only be making the added power to turn it hence almost equal from the begining so a slipping belt will just make it fall on its face at RPM
Those are some of the top problems we see your base engine is just fine for adding psi to it and they are very easy to tune most people over think it and miss the obvious.
I would go out crank the timing up make sure the belt is very tight and take it for a burn down the street Good Luck Jeff
