Here it is i have a 87 grand national, last year i had a stock turbo and stock injectors,with a 93 chip from poston. A 3 inch maf pipe and a 9 inch k@N air filter. I went to the track with slicks and a bad rear end and i could only get the boost up to 7lbs and ran at best 14:50. So this off season we put a newer rear end in, took the stock turbo off and found that it had shaft play and real bad fins. So I figured its out with old and in with the new. I purchased a rebuilt pt6376 and figured lets get 60lbs injectors and headers from poston(using the old crossover pipe) rebuilt transmission with a 2200 torque converter. A turbo tweak chip from Eric. So now i have the same problem but worse. Boost is only going up to one when break torque. And only 7 maybe 8 when shifting from 1st to 2nd. I have not had it to the track yet and can not get anywhere longer enough to let it go through all 4 gears. We did some tests, one was if the waste gate was working and put new vacuum hoses on drained the intercooler just incase any oil was in there. I need help. I do believe that this turbo should get at least 15-17lbs of boost on take of and 1 is a for cry. Any help will be greatly appreciated.
