I did a review on this product in Dec. when I first got it on another board and thought I'd bring it new light here.
The car's only mod prior to the chip was a Flowmaster catback.
The chip was purchased from http://www.BamaChips.com and tuned by Doug. Enough chit-chat let's see some numbers ...
2003 Mustang GT (automatic)
This is on the 87 oct program. The peak gains were 10 hp / 13 ft-lbs with considerably larger gains from 3200-3900 RPM. The gains were impressive but the shifts are what made it a definite Must Buy. Unfortunately we were unable to test the 93 oct program that day.
In January I took it to the track and managed a firstname.lastname@example.org with the 93 oct program and the addition of a Prochamber. This was done at full weight on street radials (stock gatorbacks)
I would recommend anyone thinking about adding a chip to give BamaChips serious consideration. I was more than happy with Doug's work and plan to get a new tune in the near future. I'll post the results at that time.
SCT and BamaChips get the from me.
