Diablo Sport Predator in 02 7.3 Excursion - Diesel Forum

I'm Currently running the Diablo sport tuner in my EX. It came with the truck when I bought it. Just wondering what you guys think of the tuner or is there a better one out there. Driveability with this tuner is kind of harsh sometimes. If you're going over bumps and your foot gets to bouncing on the accelerator it really revs the motor up and down. I've had other 7.3s and ran an edge chip and superchips on them and there was never any driveability issues. So just wondering if anybody has had any experience with this tuner, is there a better tuner, or do I have something else wrong with my truck to give it these driveability issues.

I have that tuner on my 02 superduty and don't have those issues but I only use the lower settings.

What revision of the firmware are you using? I think mine is currently the 9r03 and I don't have those issues. Would love to get a DP Tuner, but this works for now. Depending on how old your tuner is, you may not be able to upgrade without sending it in and paying for a memory upgrade.
