brought us is super nice 2016 Hellcat for some upgrades . He decided to go with our custom camshaft and True Flex fuel tuning. Our flex tuning allows him to run 93 octane or e85 and the car self adjusts for the fuel . The car only makes 13.6 psi ( he wants his power increased in stages ) and it put down 888whp on 93 octane and 949whp on e85! It’s sounds soooo good too! If you’d like to add more power to your Dodge or you’re interested in converting your current setup to our true flex tuning, give us a call at 770-449-6668 or email me at [email protected]

Loaded in the stacker for two days of testing at Steele. We have Limecat and Oscar with us too! The shop is closed until Friday, but Rhonda will be on the phones and I’ll answer emails each day before testing starts. We will have plenty of videos to post up at the end of the week.

We have a HP90 twin Turbo hellcat that thinks is a Coyote Mustang 😁🤡. Hellion Twin turbos, 8000+ rpm revs and a whole lot of powa! We finally got this valve train to live after a few months of busting parts in it with our high rpm goals. It will definitely be looking for some races in June. Do ya think we will get any O/D hellcat takers or is it gonna have to race with the O/D mustangs? My bets gonna be mustangs , those boys aren’t afraid of a fat cat and they don’t have a list of stips 3 pages long. Huge thanks to Jon Sipple for the new transmission setup to let this hellcat show off next time it’s out! This converter is the bomb! Man it lets these turbos come on sooooo fast and couples just at the right rpm.
