DiabloSport Predator Hand Held Programer

i have 2000 mustang gt with off-road x pipe, k&n air intake, 3.55 rear gears (getting 4.10s), and flows. my speadometer is off because of the gears. my check engine light is on due to the rear O2s. i bought the mills for it, but ofcorse they don't work :bang: . i was looking in to getting the tuner, it says i can fix all of this. it also says i can disable traction control for good, rather than turning it off everytime i start my car. it also says it adds 15 - 20 rear wheel horses. has anybody used this programmer??? is it hard to use?? does it really add that much horse?? :shrug:

I have one and it is easy to use. There is a nice gain in the performance tune. How much? I dont know. I do know if you take it to a dyno and check the air to fuel ratio you can squeeze more power out of it by modifing the performance tune.
 
I put my Diablo tune in a week ago and yes there is a SOTP diffrence. I'm not one to believe company adds but the tires break loose alot easier. 15-20 HP might be pushing it but it does add a bit of HP. Haven't beat my personal stock 1/4 mile best yet but I'm going to try again tonight :nice: .
 
I gained 10 HP with SLP Catback, Driveshaft, and the Mail order Diablo tune... if you want HP get a dyno tune...

But for the other stuff its more than worth it.
 
The Diablo was well worth the $359 I spent just from the HP and TQ gain I got. I had it dynoed on a Mustang Dyno and they adjusted the A/F ratio and my Mach responded well to having timing removed from it. They took -12% from 4K-7K range and -6% from 2K-4K range and overall I gained 13 HP and 12 TQ after 6 dyno pulls with the Diablo. If you add all the things in that you want to do, the Diablo is the way to go in my opinion.
