Just got my Diablo trinity in today from Sean at Hemi Fever with his upgraded tunes. Definitely the way to go. His response time has been incredible. I emailed him the information he needed and had the new tunes in my inbox in under two hours. I only did one 0-60 run which was pretty bad (need more practice on launching correctly) and I accidentally shifted at 5000rpm
but, here is what it did anyway on a nearly bald set of goodyear wranglers
And by the way, this is the 89 octane tune with the Sh*tty driver mod!
