Firstly, I apologize if there's already a thread about this. Currently my browser won't let me use the search tool without giving me a "failed request" page.
Anyhow this is the problem: While accelerating WOT after peak boost has been met, the boost falls off, the surges back up, then falls off again. It's a weird pulsing feeling. Currently I'm running livetune cobb stage 2 93 octane.
Mods are: HKS uncatted upipe w/o EGT bung
SR*S turbo back exhausts w/o cats
turbo XS blowoff valve (that I want to get removed, but have no more cash to do atm).
anyone experienced this before?
