Jet Chip

[almondjoy137]

Hi. Just had a quick question about the jet stage 1 and 2 chips. Are they really worth the $200+ and are the power gains noticible? Also, Is the only difference between stages 1 and 2 the slight HP gains: stage one claims 8-12 HP and 15 lbs of torque and stage two claims 12-17 HP and 15 lbs of touque. Just looking for opinions from anyone that has one already. thanks.

I have a stage II. It shifts crisper and I like it. No real HP gains or maybe thats because im used to it now. I've had it for a couple years.

The Stage 1 is for a stock 4.0 and the Stage 2 is for a modded 4.0 with intake, header, and exhaust. I've had the Stage 2 for about 10 years and though I haven't had any problems with it, it's also been a disappointment in terms of performance gains so I'd say don't bother buying one.
I'm not sure what the JET chip actually does (I suspect it only alters the signal from the TPS in similar fashion to the Venom 400) but it didn't change the fuel and timing curves on my Jeep. Ignition timing is still 10*BTDC at idle and a conservative 33*BTDC at full advance.
