Dyno or no dyno, Jon is an amazing tuner. The customer service and peace of mind knowing I have a reliable car is well worth it to me.
Base n final numbers is all that matters. If u see the gains, drivability is good that's all that matters.
Every car Club forum has the "highest hp numbers" and none of those guys ever go to a Mustang dyno for those numbers. Feels good to see high numbers too haha.
