I would say 5 to 7 PSI. You might be able to go higher but see what happens.

 

from what i have heard, ipd, upsolute and ricca have already taken that into consideration when designing the upgrade. not saying that anything will not happen but when i got the car it had 100k on it. for the most part, its gonna be driven normally, and on occasion, ran hard. so if the transmission cannot take that, oh well, we can cross that bridge when we get there..

and tech.. i rechecked my adjustment and noted that there was a little play in the actual wastegate hinge. so i took the rods off, turned them one more time, and made sure they were nice and tight.. i noticed no performance difference. but at least i have peace of mind that i probably did the job right. i probably will send the ecu to upsolute next week... i will repost my performance notes when i get the ecu back next week. i will also have a k&n filter installed..so will see what happens.. im psyched...

 

I cannot wait to hear the results.
