Hemifever adjustments
Hi everyone, I have a 2012 JGC 5.7 Laredo with a hemifever 89 tune. I was wondering what does all the adjustment mean under up shifts? For example 1-2 at 15% App. And throttle booster ?

Re: Hemifever adjustments
throttle booster will make the pedal a little more responsive so you don't have to press it so much to get the Jeep to move lol. Lotta folks set that up to 15 to 20%. I have a tune that will really enhance the upshift and downshift schedule. If ur interested in more power, and a better trans program shoot me a pm

Hey Sean, how often do you make adjustments and tweaks to these tunes for better performance? JW if some of us may be running on the first revisions and are missing out on some performance.
