I disconnected the neg battery terminal to install my K&N FIPK today like the directions said to do. Install went alright, other than a few fitting adjustments. Put everything back the way it was and started it up. The first thing I noticed was it took a couple seconds to finally fire up and the speedo gauge taped out at 150 before going back to zero. However, everything settled in and the idle in both park and neutral was solid. I checked for leaks and found nothing, so I took it on the road. The main thing I noticed was my shift firmness was softer like stock and the car didn't "feel" like it was going the speed that the speedo was telling me.
So did I loose my tune (speedo recal, shift firmness, etc) by disconnecting the neg on the battery??? It seems like it, even though the car still runs smooth. I guess I'll have to get back on the dyno asap...
