I debated between tuning platforms and went with the Mini Maxx. Setup took minutes, live data monitoring is a big plus, and for the cost it punches well above its weight.
Ordering to installation was fast and painless. I wouldn’t hesitate to buy from Diesel Dudes again.
The parts are well built, fit exactly as intended, and weren’t difficult to install. The 5-inch straight pipe gives the truck a sound I absolutely love.
I was unsure about doing the work myself, but the process turned out to be very manageable. No surprises and the truck performs great now.
Ordering was simple and shipping to Alaska was quick. Installation in cold weather wasn’t ideal, but the exhaust quality and sound are excellent.
