I had something called platar facitis its from standing a lot and all the jumping around I do. Recovery 3-6 weeks so I may or may not run my car at IFO but I I'll be there either way . Its my left foot so the twin disc may be a little rough on my foot at first just have to wait and see trust me I wanna run the car asap .I have heard good things about Jason Hunt but have never used him for tuning be interested to hear your thoughts on him.
