Default LT problem?

Had my BBK LT's and O/R X put on about a week ago. Since then if the car sits for 4-5 hours or more when i first take off it bogs for like a minute or so through 1-3. After that its fine. Could this be a tuning problem, running lean etc? could it have something to do with the o2 sensors? Any help would be appreciated. Thanks, Justin

when you start the car, and take off for the first time, after its been sitting, do you just take off?

you should let your car warm up a lil before you beat on it, so the oil is at its best viscosity.

Have tried letting it warm for like ten minutes to see if that would stop the problem and it still bogs after i take off. This also just started after the header/x install.

Thats pretty strange. You arn't having a massive leak or anythign are you?

Are you using a aftermarket tuner? Also, it doesn't do it after you drive awhile, let it idle for a minute, and then go again?

I wholeheartedly agree. I had a huge leak and my car ran like crap. I finally went in and changed the gaskets and slapped some stage 8 bolts on it. Ran smooth when I started it up but the Jury's still out on driving it around because I won't be able to drive it until Wednesday.
