thats definitely a positive thing when dealing with Shad, if there is a problem or a headache while doing the dyno tune, he just shrugs it off, stays calm and cool and will help ya fix it right there and still get your car tuned. I have had many problems with a setup happen while doing a tuning session, Shad usually had the part to remedy the problem or he would start tearing something down while i ran out and got a replacement, and we would always end up getting the car tuned and back to good operation, big big props to him. Hes been in business for a long time for a reason.
