Wichita elevation is around 1300 feet. I ran a 13.04 with a different tune, a smaller CAI, a stock throttle body. I went and spent a bunch of money upgrading my CAI, getting a ported throttle body and hand porting the rough edges and casting marks in my intake manifold. I then made the mistake of going to a stock predator tune and overiding the unknown custom tune that was on my jeep. Afterwards, I was running a 13.3...I was pissed. Since then, I had Johan make me a tune and I tried it before the strip closed in November and ran two runs, both at 13.1. It has been extremely frustrating to say the least, especially since I'm the one screwing it up. I am about ready to just put nitrous on it, but I really would like to keep it naturally aspirated with "no tuning required" bolt-on parts. I have been apprehensive about putting an underdrive pulley on, because I have a $4,000 stereo system in it and hate to pull so much juice sitting at an idle with it spinning the alternator 25% less. I guess I can just add a capacitor if necessary.
