Hey everyone,
Just got myself an '04 Cobra and it accelerates and idles fine. However, when I peg it and go into full boost (say around 3k rpms), the car either sputters a little bit (kind of like a slight shuddering) or it'll surge a little bit, making for a non-smooth pull to 5 or 5.5k rpms. The power is pretty much there and the boost guage hits '8' psi, but its not a clean pull.
Going to the dyno this week to check out a/f and things like that, but does this sound familiar to anyone? Hoping its just a/f, plugs or belt slip and nothing more...thanks and I look forward to contributing!
Oh sorry - stock pulley, intake and exhaust, 40k miles...
