allright, my car runs great and strong or so i thought. Went to the track and ran only a 14.5, when pushing the to its extreme limits. Not bad time, but chitty for having all the bolt ons in my sig right? well after this happend i then started payin close attention to the way it was running. (listenin more etc.) i have now noticed that my car is missin throughout the higher rpm range in 2nd and 3rd gear. its not terrible but it is noticable. i got 65,000 on it and i was just wonderin what kinds of things other than tune up stuff may need to b changed or help me with a lower better E.T.


BTW 14.5 was not on nitrous


Any help is highly appreciated

 

Hesitation/Missing can be a number of things, maybe plugs or wires or possibly your un-vented optispark, but outta those three, I would try the tuneup and possibnly an LT4 Knock Sensor. Also it would be good it your got some Nittos or BFG Drag Radials.
