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.

DiabloSport inTune i2 Tuner Reviews

It's okay, but I've used better.

It's not a bad little tuner, but for the money I wish it would be a little faster. My SCT tuner loads tunes in only a minute. This one however take 3-4 minutes. Really racks up the time on the dyno, which cost more money.

I purchased this for use on my 2008 Mustang GT. I had to download a newer version of software from the Hypertech website before I could install it but that was quix and easy. Once installed I was pleased with the new level of performance that it provided on this vehicle. I installed it after installing a K&N Cold Air Intake system and Gibson exhaust system. This unit tied everything together and the sum total of performance gains was quite impressive, great tuner.
