I had poor results with the Predator on my former 05 GTO, around town the throttle response was improved, the car "felt" quicker...BUT...the stock pred tune detonated and pulled timing consistently when going WOT. Things "seemed" to get better when I adjusted the slope, took care of the timing pull but was disheartened when on the dyno it was below my previous stock pulls by -20rwhp. We loaded back the stock tune after a few lousy pulls and gained all the hp right back (340's)......gave the predator another try a few weeks later with a custom email tune and again it fell a couple hp short to the stock rwhp.....loaded the stock tune back in the car, enjoyed the increased *stock* tune hp and put the predator up for sale.....

IMO, nice tool for logging data/clearing codes, but left me very disappointed in making power.
