I have been testing some new tunes for Sean over the past few weeks, and I have to say that I am very impressed with how strong the truck is running. He has made some adjustments that gave much better low end power. Now I'm just waiting on this TX heat to go away so that I can get to the dragstrip.

I loaded and drove the new hemifever tune that Sean sent me earlier and I have to say wow, it's freakin awesome!

Especially, the launch... no lag at all. My 5,000lb truck is like a jack rabbit off the line! Lol

I didn't have a chance to do much in the way of wot yet (to many Sunday drivers), but I can really feel the difference from my original tune to this new one.

Thanks again Sean and great job bro!

Sean, I took my truck out on the freeway today for about an hour.
The truck pulls VERY hard through all the gears. I got it up to 120 mph for about 5 seconds, and played around with it between 70-100 mph...
Also, the shifts are quick and firm.
Killer tune bro, thanks again!

I'm getting ready to purchase a Diablo trinity with hemifever tune but I'm not exactly sure how it works being my first tune. So do I install the hemifever tune into my truck then send back how it's doing via email and he makes adjustments I think is what I've read ? I have a 2014 R/T 8speed and excited to get it and dial it in. Also need to order the 180tstat too. I should probably email hemifever

Well I found out that I installed the update in the wrong way so I wasn't pleased with the performance, my fault. After a few emails from Sean I finally got it right and wow!!! what a great tune and improvement. I went out to a back road to see if there was a difference. From a stand still I floored it, spun the tires through first and most of second gear. Once the tires stuck my front end lifted and she started pulling hard. She revs high, shifts are firm but smooth throughout the power band. I feel more in the mid and top end now compared to my first tune. I can't wait to run her again in a couple days after everything sets in. Great job Sean, keep up the good work.
