    need tuning help

    does anyone know what my problem is. my car stumbles at around 2500 rpm for a second. I have a aftermarket intake, lt headers, custom y pipe without cats, o2 sims and a catback exhaust. Do I just need to tune the car?

    sounds like a mechanical problem rather then in the tune to me.

    sounds like a missfire when engine is under a load.best thing to do is hook up a scanner and look for excessive missfires on cylinders or coils.could be something as simple as a plug wire or bad plug.

    high oil pressure

    in addition to the stumble at 2500 rpm, the car also has high oil pressure. when its cold and warm it sits at about 60psi and under load sometimes almost reaches 80psi. I have been taking it easy on the car until I can get it to a dealer service deparment but just want to know if anyone has experienced this and whats the probable cause?
