hesitation off line

barrycobra · 02-07-2013, 12:36 AM

Hi everyone! I just got 2005 ford mustang 4.0 v6 auto and took to track for first time. I have bad hesitation when I floor it causing lousy reaction times of .098, .135 & .194 even though I deep stage and leave beg of last yellow. I saw a TSB about hesitation when passing and was looking to have local dealer reflash my PCM for about $125 because I can't afford $300 for Tuner. Would this also help ET because I'm only running10.40 to 10.50 et in 1/8 mi which is only 16.30 in 1/4. I was trying to run True Street at NMRA race next month but slowest class is 15..00 I used to race 1969 mustang with 429 CJ& this is first time dealing with no accel cable. thanks for advice Barrycobra
