phil from phdtuning here...I tried to make an account with that name but could never get it verified but here we are.
Tuning the toohighpsi reflex controller couldn't be easier. I'd hope any competent tuner could get it done. It takes a little bit of thought before you get started to make your life easier (as a tuner), but once you get everything lining up between the tune and the reflex adjustment couldn't be easier. I have absolutely zero hesitation recommending it to anyone, and if anyone needs help with it let me know
I appreciate the mentions from Mike and Greg. It's good company to be in.
