What happens if my numbers are better then your tuner can produce? I've wondered this about these detail days also. Do they tell you a Shamie sucks and you should not let your wax dry on your car. Do they tell you about the master blaster.
Just confused is all. Good luck with what ever it is you do.
LOL Yes you are confused. If Ed is tuning at the dyno day your good tune will become a great tune. You sound like you have had a few bad experiences. I suggest not waiting for the dyno day and getting over to see Tim now to get your tune optimized.
