05 GTO + Predator

Looking for any input on Diablosport predator tune..

I was talking with a dyno shop out of Richmond (http://www.performanceautosport.com/dynojet.asp) and they said they have tuned two stock 05 GTO's in the last week and did not gain any additional horsepower with the predator tune.

Thanks.

Thats kind of par for the course for a predator.. They dont even have transmission controls for the 05+!

Had my Predator for about a month and engine feels a little stronger, but nothing major. Was able to eliminate CAGS and gas mileage is about 1-2 mpg better when I'm not on the gas pedal. Worth it?? Probably not.

I was rather disappointed by the predator for the 2005 GTOs. It can't adjust for ring and pinion or wheel/tire size changes. I did not notice any improvement in power (did not dyno it). The real time data portion of the unit does not appear to work (as far as I can tell). I have several questions for DiabloSport, but my questions to them have gone unanswered.

I installed my predator and dynoed it. It only had 402 HP at the engine. Also, it made my T/C not as responsive and spun out into a ditch at 50 MPH. Trying to get a refund now.
