DiabloSport Predator P2 Tuner Reviews


Reviewed By Richard R (Evans, GA) Reviewed for a 2003 Ford Mustang —11/7/2008 5:30 PM

After owning several 5.0 Mustangs,I was sorely disappointed in the 4.6,namely low end torque. The Predator was a miracle worker on my '03 Mustang GT. It drives like a different car. Where it used to just barely chirp the tires going into second gear, it now breaks loose, even with traction control ON. Cruising in fourth gear around 55-60 MPH it will now accelerate nicely without dropping back into third. I feel the Predator offers plenty of bang for the buck. There is nothing else I could have spent that amount of money on and achieved those results. Installation was easier than I could have imagined. Car is bone stock, with only Flowmasters and AEM Cold air kit. I recommend this product to anyone looking for horsepower and torque at a bargain price.

Pretty good buy. Chip works pretty good. Stiffer acceleration and smoother gear shifts
