ok what the hell!!!

well i hae had my truck apart since january and i have done alot to it and it will probably only run a mid 13. I dont understand it! I am runin 15lbs of boost and everything seems to be runnin fine on the datamaster. For some reason I have realy shitty bottom end power, but a lot of top end. Does anyone have any guesses on what is the problem.

The only thing I can think of is the old production line rule. Back in 91 you could line up 5 stock SY's and one is just going to be faster than the rest and the other 1 of 5 is going to be a lil slower. All in the guts. Of course, when you rebuild things, sometimes they are never the same. 0X

go out and actually see what it does and start tuning from there.

I'd venture to guess you are spooling up slower with that bigger turbo.

The TC should be helping spool up, but like they said, get some datamaster runs and watch your boost, knock etc.

Check your base timing too and make sure you arent retarded...
I mean make sure the timing isnt retarded.

the turbo spool up time is great al the way to 20, but it just feels like it is out of power. I was sopposed to go to the track today, but for some reason it started missing out real bad. So i am still tracking the problem down. I have a few datamaster runs with 10 lbs of boost and with the problem that i have now if someone could look at them and tell me what they think, i would appreciate it.
