im reaching about 19-20 peak and at redline it tapers off to about 16-17. that's what I don't get is with all of my supporting mods and bigger turbo im not even getting better than stock. and that's with the manual turned all the way up. im thinking its a tune issue but is it because the computer wants to read from the stock boost solenoid, and im throwing something else at it? thanks for your input

 

you do a boost leak test?

have you looked at preload on your turbo? it might not be preloaded right and you wastegate could be cracking open a little bit.

 

no boost leak test, doing it soon though. and how do I look at preload?
