Testimonials
“John is very knowledgeable about HP Tuning. My wife and I bought an H2 Hummer and John was able to get us on the road. Previous owner swapped out and heavily modified the engine. In doing so, we were not able to get Emissions to pass. After I added a couple cats and O2 sensors that were deleted, John tweaked the ECU and litteraly cut the emissions in half. The engine runs smoothly and the idle has smoothed out. He drove all the way to Greeley to get us going.”
