392 Flashpaq

[cball508]

Hello,

I had the flashpaq for my 18 JL 3.6 and I liked it. I recently received an email about the flashpaq being available for the Wrangler 392 (3876-JL). I'm curious what gains you're seeing on your programs with the 392? Nothing is listed on your site. It just says "real power gains you can feel." Any help/info would be great.

Thanks,
Chris

Livernoise tune picks up 40hp and 45ftlbs, from comparing their other tunes to superchips tunes that have dyno graphs, I’d bet their tune is 20-25% less. Say 30hp and 35ftlbs..

I spoke with superchips at bantam jeep festival. If I remember right they said around a 20hp gain. I asked about warranty issues and they say you can go back to factory and the dealer wouldn't realize it was ever tuned. Im gonna need to look into that further before I choose them over livernoise

I have to be totally honest....there is no way gains of 40 rwhp were found on a 392 Jeep unless they started on 87 and tuned it on 93...maybe. We tested on 2 different vehicles and found them to be rather aggressive from the factory and very spark limited with the added load of the heavy tires, etc.
There are solid improvements to be had, but huge peak gains like that are not among them.
