I don't think your going to need thick skin, your pipe is making power Mitch. I don't see how anyone wouldn't be happy, big power at a good price.

When I was pointing out your possible hp swing, it was more for you to keep a eye on. Your at the point 2 hp is a big deal. So repeatable dyno pulls are important now. So when you drag the quad into Bennie weeks from now with the same setup, it should make 65.83hp. If it doesn't you need to know why, tire pressure, hold down strap pressure.. if all the dyno setup checks out. You go through the quad. Drain & switch fuel. You end up sending a kid to two different gas stations with two cans and remix then re-dyno and find Shell mix makes 2hp more then Clark fuel. Or it didn't but now you know. Do all you can to get 65hp without changing your quad setup. Everything checked and switched and say 64.5hp is it. Then start tuning. After all your tuning is done, say it make 3hp more at 67.5. You should put the old setup back in one last time and verify a 64.5 hp base / start. If it doesn't, your back to why and digging into it
