this happens from a dead stop and from a roll. when i floor the car i can hit and hold 18- 19 psi until redline on my high boost setting. if i slowly get onto the throttle until its floored i can hit and hold 22- 23 psi unitl redline on my high boost setting. why is this happening? is there something wrong? thanks for all responses.

even if i disable the boost controller and have the wastegate hose pulled it still happens the same way. i can hit and hold 22 psi but only if i slowly get on it until its floored.

i'd say it allows more time for the turbo's to spool and thus produce more boost.

i was thinking that too. maybe this is happening because of the 3800 stall torque converter i have. maybe the boost doesnt have enough time to build up because the rpm's move too quickly when i floor it.

yea, im bpu+++ with a 3600 stall. i usually dont run them past 18 psi unless im at the track. i might go as high as 20 psi if that. it actually makes a difference on my car. but i would just like to figure out whats causing this to happen.

Its not worth it, over 18 PSI they are very inefficent and you are damaging the turbos.

I wouldn't think that the stall would have anything to do with it. Remember, the car is still building boost even when the converter is slipping. Its not like its a single that is spooling later.

BTW, I think we all know that 20psi is not good for the turbos but niether is 18 or 17 or 16. It makes more power and that is the trade off. I pushed my stockers to the limit of their efficiency to get my car going as fast as it could go.
