I installed the Trinity Stage 5 full exhaust and the Dyno Jet Tune from Trinity. What a huge difference. The midrange poor is about the same, but the power from the beginning is a huge difference. It eliminated the reverse safety switch, and the engine temp runs in the 170's now. Not sure what the temp will be in the heat of summer. I bought this from https://rad.parts/ I believe if you give these guys one chance, You'll see why I use them. Great small business that wants to earn your business.
