I am stoked! Thank you ALL for being a part of the solution. It burns me up to know the amount of great engines out there being ruined by the ridiculous laws and science being forced on great Diesel engines. No doubt about it, there are less than a handful of un-needed factories blowing more pollution into the world than ALL of the diesel engines combined. Thank you again for all you do! God speed.

Mike

Thompson

Everything in the kit ordered worked great! I am a happy customer and will likely purchase again!! Thanks for the great products. Thank you for your time.

Did exactly what it is meant to do... go me back on the road w increased efficiency! Beyond happy with the tuner and it's ability to monitor drivetrain functions while in use! Worth every penny!!

Baros

Great company to work with. I had a problem with my order and they took care of it right away. I would recommend them to all my friends.

10/10. I had a little mishap with the EGR kit getting shipped but after a late-night email, that was responded to extremely quickly. Customer service top notch. Install quickly and easily. It is a great product and a great company.

I pull a 48ft car hauler with my 2014 Ford 1ton, 5.9mpg and the truck would overheat. Installed the delete kit, no more overheating 12.8mpg. AWESOME THANKS

Yes, I am definately happy with the products and services I purchased from you! The shipping was fast and secure, arriving within 5 days of ordering. Thank you for a great shopping experience, I have several friends looking for similar products and services, and have directed them towards your company. Thanks again for everything-

I am more than happy with it. I have completed the DPF removal and straight pipen install. I have not removed the EGR. I can say that I have picked up more power and 3 more mpg towing. I have an 8k pound bumer pull camper. There is a little black smoke when I punch it; none if I drive "normal". My wife said it is louder, who asked her. I have been on the fence but your price and the extra $100 off, with free shipping was the factor. Thanks for the entire process from ordering to installation videos.
