Here is the story. I have 2 settings on my profec b spec 2 as you guys know. low and high. my low right now is set for 13 psi and my high is set for 17 psi. my car is tuned for 19 psi and i am trying to set my max boost up to 19 psi. the way the boost controller works is by a percentage. my 13 psi setting is 27% and my 17 psi is 41%. Does anyone know the percent for 19 psi on the profec b and the greddy wastegate that came with my t78 turbo kit? I believe i was told that the percentage from the boost controller has something to do with the duty of the wastegate. thanks in advance.

why not slowly increase the setting until you're just under 19 psi? Turn **** and press to set new value. If you go up 1% at a time you should be fine.

its the middle of winter time with snow. I wish i could. im just getting prepared for spring time.

 

really the only way is to drive it and test it.

 

well it should only take you a couple of pulls to get so it's not like you'll spend a ton of time trying it out.
