Yes, DrDiff is good on the phone or email. I had a install question at 11:30pm one night that stopped the process, I emailed him the question, and 5 minutes later he emailed me back which allowed me to complete the install that night...also a steering box upgrade from FirmFeel helped a lot. I went with a stage 2 box but I think I would do a stage 3 if doing it over again.
