Who do I get in contact with for the chip programming? Also I looked one of the forums about doing it yourself. How much and what is involved in that. Also I am looking into the manual boost. I will get pictures of the engine compartment up. Thanx

My bad, it's a GT28RS. And the boost I am reading is from a aftermarket Auto Gauge. The stock one is off the charts. Also should I get rid of the MSD all to gether or just the coils?

Is there another way to put more than 14.5# without junking the comp? Becaus emy gauge is reading 15#, but the turbo is not hooked up factory.

Why would I want to get rid of the MSD? I have a hotter spark with the MSD box and coils. I am almost ready to junk the computer and go with Holleys comp, but thats alot of money. I will look at the turbo but I am almost positve thats what it is. If I can get it runnig properly, I'm hoping for at least 25#. It does run at 45# of fuel at idle though, sorry.

Sorry its a Garrett GT45RS.

Yes I have a top gun chip and no since I have done the motor work it ran fine with the original turbo. The turbo has also been changed over to vaccum no computer involvement so when its running 15 PSI the fuel pressure is still at 30 PSI. It only happenen when I put it to the floor.

I have a 90 Grand Prix Turbo with a GT4RS Turbo set at 15 PSI of boost. Bored .30 over with polished heads, roller rockers, Comp Cam made for a 3.1 turbo. 29 Lb injectors, MSD, and a top gun chip. When I put it to the floor it spits and sputters. But if I lay into it slowly it runs fine at 15 LBs. Can some one help me?
