8.1L motorhome PowerPack: Very satisfied!
2010-11-30
I had your exhaust and intake systems with the OttoMind programmer installed and am very satisfied with your product. I get @ 2 miles to the gallon better fuel mileage while towing a 2010 Toyota Yaris. The difference is definetely noticeable. Good engineering job!
