Hey Deuce, as I explained on the different threads about MHP (couple of years ago) there was a power improvement, however it wasn't worth what Andy and MHP were charging (over $2,000). I believe my car dynoed 19HP more after the tune, I don't have car anymore though.
I was wanting the file from the computer. Did the Dyno shop give you of a copy of the computer file? He can down load it to a jump drive. This way I can pull up A/F TQ and rpm separate.
