Yeah I improved .003
My 60's were way off and my 1-2shift was occurring at 5750. When my car was tuned, it was programmed to shift at 5750rpm because by the time the 120,000 mile + tranny got it done it was 6400rpm. Well, I J-modded the tranny yesterday, so guess when it shifts now? 5750
Thats why I'm not too upset about only improving .003. Between short shifting, worse 60's, but picked up over 2mph....it'll be there, just might take some tweaking. I have already wrote 3 more tunes since I got home from the track. NMRA Michigan will be a great test. 12.70-80's :laughing7
