I have a 1993 twin turbo automatic. What it is doing is it boosts to 5 lbs and then goes right back to 0. Will not go past 5 lbs no matter what i do and always gets cut back to 0. Anyone have any idea whats going on. Here is some background on the car. It was single turboed and put stock twins, the twins that came from car with only 61k miles back on car. Car has a Greddy BCC, Full Exhaust and Greddy 3 row front mount. It is on stock computer and does have EGR removed (could that cause a problem?) Any ideas or something to check or try would be greatly appreciated!
