I'd like to thank Cal and Holly Hartline for making special provisions to add an extra leg to his trip to come and tune with me. Being in a state like Montana it's hard to get people who have knowledge of any after market tuning, especially XFI, so his help was pivital. Not only did he add and extra 12 hours to his trip, he missed his 19th anniversary. Cal and Holly thank you for your selflessness in the car world, and more importantly, sacrificing your personal time for the pleasure of others. Happy Anniversary and thank you. These are class A people to deal with for any high performance purchases.
