All I can say is WOW! I hooked up wtih Brad from Rvier City Diesel and they got me dialed in on three tunes for my Livewire. I got the 485rwhp, the 585 Race, and the 585 Lope Idle tune. I loaded the 485 tune this afternoon for an evening commute and the truck feels great compared to the Extreme Tune I was using from SCT. The tranny feels nice and quick and the shifts are firm but precise. Big thumbs up from me on what I have seen so far. I'll also be trying them out at the track this Sunday so stay tuned.
The truck will go on the rollers tomorrow if the weather is good or Saturday if it's raining (mobile dyno).
