I just recently had my car tuned after installing a JLT high boost cai and going to a different shop I made 21rwhp more then it did on the first pull.
Car made 560rwhp on a mustang dyno with 2.3 whipple 17psi and 2 degrees less timing car had been tuned at Pro-dyno before and was way rich up top and had bad hesitation between shifts good thing I got it tuned because Pro-Dyno failed to tell me my fuel system was tapped out at 5k rpm he just threw more fuel in it and let it go. So I wouldn't go to them again
