Night-and-day difference! SOTF Level 5 (+220HP) is insane blew my buddy's deleted Ram away. Tune files loaded in 20 mins.

Kit arrived with a scratched tuner (cosmetic only). Level 4 tune's power band is perfect for mountain towing.

EGR delete fixed my recurring coolant loss issues. The 4 race pipe sounds deep but not obnoxious. Truck feels 10 years younger at 180k miles."

Night-and-day difference after ECM swap! SOTF Level 3 (+120HP) is my sweet spot. AutoCal V3's live tuning saved my turbo from overspooling.

Complete kit with everything promised. +100HP tune is perfect for daily driving. Bypass cable included for my 2020 - no check engine lights.

Complete transformation! ECM swap enabled SOTF tuning I couldn't get before. EGR delete dropped my EGTs by 250�F when towing. Worth every penny.

Complete transformation! The race pipe fit perfectly and the Mini Maxx's tuning options gave my 2012 new life. Fuel economy improved by 2MPG highway.

Absolutely worth it! The CTI tuner is a game-changer. My Cummins feels like a beast now�way more torque and smoother acceleration. The 4 inch exhaust sounds aggressive without being obnoxious. Installation was straightforward, and the tuning support was top-notch."

Deleted my 2020 Sierra's DEF system finally no more fluid refills. Street Tune's +60HP is noticeable instantly.
