Mods are in my sig. Problem i've been having lately is that i'll go WOT from say 30 mph and i'll hit about 17psi boost. at 7k i'll shift to 3rd and same thing. Problem comes around about 6k rpms my boost will just shut down to about 7psi and never come back. sometimes its after the car is warm sometimes it does it when the car is still gettiing up to temp. any ideas? i was thinkin belt slippage but why would it do it so spuratic and have no ryhme or reason to it? also why would it be slippin if that is the case? i have stage 2 belt on a 2.8 which shouldnt be slipping. any other things it could be?

 

Dead intercooler pump and the tune cutting boost for high IAT2's. Do you have anyway to monitor the IAT2s to see if they are getting too high?

 

INterceptor gauges moniter this Just wondering though, what is "Too High" on that temp? Ive seen mine up to 120.
