We began our tuning journey in 1997, modifying Chrysler ECUs for the 1987-1993 Chrysler Turbo car platform. Over the last 28 years, we have created custom ECU calibrations that make the most of your aftermarket parts. From factory reflashes to custom development projects and in-house ECU unlocks, we have you covered with our extensive calibration library. In-house, we offer live dyno calibration services on our in-ground Dynojet for cars up to 1000 WHP, or up to 6000 HP on our Mainline Prohub 6000.
Drag racing is our passion. We offer professional consultation, tuning, chassis setup and team management programs to make you competitive and keep you there. When it comes to the parts that we sell, the track is our proving ground! Street, strip or full race we have a package to meet your goals and we get you to the finish line!

Our crate engine program is the result of a development initiative that has spanned over 15 years. With extensive experience in both dyno testing and real-world performance on the racetrack, our expertise is unmatched. We have rigorously fine-tuned every component to ensure maximum power and reliability. Whether it’s pushing the limits in a controlled environment or facing the intense demands of competitive racing, our crate engines deliver exceptional performance that stands up to the toughest challenges.
