Chipping a 4.0L

Just wondering if anybody has any experience with running a chip in their TJ.

Is it worth looking into?

Kinda like chipping your john deere or wheel horse lawn tractor IMO. If you want a faster jeep build or buy a stroker, if thats not enough add a super charger. The factory pretty well maxes out the stock engine for a good balance between performance and economy, adding headers and better intake is more useful. If you do one side of the engine you have to do the other to benefit. While a lot of the factory diesels may be detuned so that one of those controllers can work miracles I don't think the 4.0 suffers from that same condition.
If you want better street performance 0-60 regear the beast, you'd be amazed at what going from 3:53's to 4:10's feels like without changing tire size. Not to mention how fast you can go thru a set of BFG AT/KO's...

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.

yea but thats on top of the RE throttle body which prolly gave it most of its improvements.

A guy on Fourwheeler.com forums just put a jet ship in and he said it definatly gave the jeep a kick in the pants.

I put a jet stage 1 in mine that a friend gave me and I couldn't tell anything at all. I didn't notice any change in power or MPG. I haven't done anything else to help out or to hurt, but I personally didn't see anything at all with the jet chip.
