A good product, but it could be better
installation was easy and simple. Beside drilling in exhaust manifold for egt sensor and dashboard for the switch, everything else was plug and play. Which is great when something go wrong, just pull over and disconnect three wire harnesses, plug in original and drive on till you can investigate the problem properly or call tech support; Which I had to do. I would write the whole experience, but I'm limited to 500 character. Let's just say it was a three weeks of drama so far and good result.
Makes a huge difference
My 83 F250 is way more responsive. I could barely keep up with traffic going up steep grades at highway speed. Now I can pass cars on the same grade. The instructions aren't great and some parts didn't fit right. I had to grind about an inch off the inlet flange foot to get it to fit. Overall a fun project and performs great.
