Jet Performance Module (Stage I)

[FlexinCherokee]

I've run across these "performance chips" on quite a few sites and in a handful of aftermarket performance shops. I was curious as to if anyone on the forum is currently running or has run these Jet modules in the past. The Stage I module claims "Better throttle response and improved MPG". I'll leave it to the users to help me out here, any feedback is much appreciated, thanks!

I loved the Jet2 in my 94, but the Jet2 in my 96 with the same mods was so-so.

did you see any kind of improvements in fuel economy? I have a 2.5" Flowmaster exhaust, K&N Drop in filter and LS1 injectors and I average 16.6 City

I used to run a JET Stage 2 but it turned out to be a disappointment. I eventually removed it when the rev limiter began to mysteriously creep lower.

I didnt really compare before and after mileage, but didnt get worse mileage(unless i put my foot in it more).

Hmm, I see. I was just trying to gauge the likelihood of one of these modules helping fuel economy at all. Thank you for your input!
