Customer Reviews

Added the cold air intake - turbo spools faster now. Mini Maxx's shift-on-the-fly works great. Stainless pipe shows no rust after winter.

Full support package worth every penny. Race pipe sounds aggressive but not obnoxious. EGR delete took 3 hours with basic tools.

Missing one EGR gasket. +130HP too aggressive for stock trans. Still, +65HP made noticeable difference in fuel economy.

Missing one EGR gasket. 50HP tune barely noticeable. Still, no more DEF system headaches.

Kit does what it says, but the O2 sensor wiring was short. Had to extend it. Otherwise, solid performance.

Complete kit as advertised. Turbo-back exhaust sounds deep. Mini Maxx's live gauges helped diagnose a weak injector.

Install instructions could be clearer. Economy tune only gained 1MPG. Still, no more DEF system headaches makes it worth it.

Shipping was faster than expected! Kit arrived well-packaged and complete. Noticed better throttle response after install.

ECM swap process was flawless - had my tuned ECM back in 4 days. SOTF switch works perfectly with all 5 power levels. Truck runs like a beast now!

Mini Maxx V1 tuner woke up my 2011 3500! The 4 race pipe sounds aggressive and the EGR delete dropped my EGTs by 250�F when towing. Perfect kit for these early 6.7Ls."

Unlock Tool Upgrade is revolutionary! My 2020 Silverado retained all factory settings - no ECM swap needed. 150HP SOTF tune is terrifyingly powerful.

This kit completely transformed my 2022 Ram 3500! The power gains are insane, and throttle response is so much sharper. The live tuning session was smooth, and the team at DPFdelete really knows their stuff. Went with the 5 exhaust, and it sounds mean. Worth every penny!"
