I have a device that was not purchased through them and was having problems with a tune and they took the time to help me, and that is amazing customer service.

Just did my truck with ecm and tcm tunes. Truck had no issues. Fired right up. And ran so much better!!

Was planning on getting tuned with another company when I found Sasquatch diesels, tuning with them was a breeze, extremely easy, they were cheaper than any competitor that I found, running on a 30hp party tune and getting 3-4 mpg more than my previous tune, 10/10 recommend!

I cannot believe tuning got my 2019 gmc sierra 2500hd denali crew cab to 27.5 mpg checked at the pump! Wish I could attach the pictures! Ordered the tuner, sotf tunes, full def, canbus plug kit, egr removal kit, and 3.5” down pipe, 4” exhaust with 4” muffler and kept the stock tip. Programming when smooth as velvet and not one code has popped up in 3k so far. I couldn’t be happier!

5 Star,Ordered the exhaust expecting it show up in a week or two but it came in 3 days! Super impressed with the quality of the stainless exhaust and included clamps and hangers! I’ll be coming back to Sasquatch Diesel for more parts!
