Engine/Transmission (1998.5 - 2002) Variing peak boost numbers? Long but need advice!

[JaMan]

I just dynoed my current settup last weekend and was very dissapointed 366/800 I belive I have a problem with the Comp drag. Before I could muster 39-40psi then the wastegate would open and drop to 37psi , I liked that. Then it started going to 35psi tops so I checked for a boost leak none found. Then I dynoed low and there was no difference between 3/5 and 5/5 so I unpluged tap wire on way home to EZ mode and not much difference. Plugged back in later and I hit 40psi again WTF, bad connection at wire right, well next time I drive it I only hit 36psi, so I turn comp off and back on and hit 40psi again, I am confused low on power low boost maybe bad connection right , then how would turning it of/on help? And why no difference in levels? Sorry so long but I am confused!





Thanks so much, Jared

Next time your up in this area, we can swap our comp boxes and see if it still has a problem.

You may not have enough air going in to burn all the fuel. A lot of times if you have the same power on the low end of the box as you do on the top the problem is not enough air.

I had a comp box replaced that was acting like yours. Not much if any difference in the sop meter between 1x5 and 5x5.

My gut feeling is that it is the comp acting up.
