Wow, that thread...
So back to the question: does anybody have experience with chipping a TJ?
(and to answer the oncoming questions of what is in the ride: 35", 4.10's, 4.0L, NV3550, STaK 3-speed, 1310's front, 1310/1350 flange rear, D30 Front, Super 35 rear, ARB F/R, AirRaid Intake, Flex-a-lite fan, dual-bat, 8-ball shifter knob, etc)
Overall objective is to get a little additional power without having to regear. Yes the 4.10's are a little on the high side (should be 4.56 or 4.88), but I find it works better in the city MPG wise. The STaK's 3.05 and 5.44 gears more than compensate for the difference of 4.10 vs 4.88's.
