I have a serious problem. When I take off in 1st or 2nd my car studders a little bit. It is really noticeable when I mash the pedal hard. It does work throught the studder... in other words if I keep the pedal mashed it will stop, but it is really noticable. The car didn't do this until I installed my JBA Shorty Headers, RT High Flow Cat, 2.5" Flex, and Borla Exhaust. I have checked all the fitting places to make sure there are no leaks? I replaced gaskets.

Is anyone or has anyone experienced this phenomena?

When you installed your mods did you disconnect the battery? That way, after you get your mods on, and you reconnect the battery the ECU will know there are new parts and allow for the car to flow the extra air.

hmmm you put your mods on about 7 months ago. Did it start after you put your mods on or did it just start recently?

Is your intake tubing hooked up correctly and tightly. My intake tubing came disattached slightly from my throttlebody was was causing surging and major idle problems.
