Need more feedback on this, anyone else have this tune and feedback on fuel mileage, engine response, trans shifting?

Ive said it multiple times in multiple threads. Its the best thing you can do to your Jeep. The transmission shifts SO much better with HFT's tune and the engine response (ie: torque management REDUCED) is much better. Fuel mileage? There isnt much you can do to gain a ton of fuel mileage. I saw .5-1mpg gain which is really nothing. If you are looking for MPG with a Hemi, you purchased the wrong engine.

I mentioned earlier that my canned Diablosport tune actually caused me to lose 1-1.5 mpg but when I went with the Hemifever Tunning, it actually increased about .5 above stock for city driving.

The engine response and transmission shifts are so much different that stock and also with canned Diablo tune. The power-band is strong all the way up to the redline with this tune. You won't regret it and the additional cost over purchasing a Diablo product is minimal...$125.

Its actually free if you purchase a Trinity tuner from him directly. Trinity costs $599 (set by Diablosport). HFT includes the tune in that price. Theres a smaller $40 or so fee over the cost of the Intune if you purchase that from him.

Thanks for pointing that out. I already owned a Trinity so to me it was $125. Best money ever spent!

How do you install into our trucks? Do you just plug in, then take it out? Or do I have to keep a monitor installed in the truck somewhere?

You don thave to keep the monitor installed. You can install the tune and pull the thing out if you want. If thats what you are looking to do, look into an InTune DCX. It has the same capabilities as far as tuning as Trinity but it doesnt have the extras.

Its easy to install. Just plug into the OBDII port and follow the instructions. Select your tune and select install.

I recently purchased the hemifever tune and I'm very pleased. I don't think my MPG changed very much but the GC shifts much better, up and down. Sean Powel is great! The first tune he sent me needed to be tweeked, I didn't like the tweeks so he sent me another tune. He worked with me like he was my best friend. I think we had about 30 emails back and forth.

I was on the fence about going with a Pentastar V6 or the Hemi V8, but the available tuning option for the V8 seals the deal. WK2 guys with the V6 seem to be out of luck

RIPP will be making a kit for the JK's but that doesnt mean itll work on the WK2. Still need the tuning for the WK2 v6........ And that remains to be seen.

I have a 2011 GC Hemi that has what people are calling a "fish bite" more noticeable when coming from a complete stop turning left... Has anyone had that and did the hemi tune correct the problem?
Thanks!

Don't quote me but I believe the tune is mostly improving the transmission shifting. If you read all 3 pages of this thread, everyone seems very pleased
