Ok, now this is happening. say im driving at 3k rpm in 2nd or third gear(this happens pretty much any gear im in), if i punch it at 3k(rpms are just for example as this does it not only here) it will rev to say 4k rpm then drop back down to 3800 rpm then rev again over 4k. does this stay or go away after the ECU adjusts? please tell me uve had the same happen to your car after installing an exhaust because this is starting to worry me, A LOT. any feedback on things like this would be greatly appreciated.
