Diablosport Forums

Hey I have read 1 or 2 posts that seem to be applicable to me as well. When I bought my diablo in 2007 and tuned my truck it had so much power and increased fuel mileage. I was ecstatic. Then several years ago a Ford dealer "updated the software in my vehicle". After finally installing the update to my diablo and installing on my truck, I am less then impressed. It's almost like I haven't installed anything at all and I'm not realizing any fuel mileage increase. I even restored original back up and then reinstalled the sport tune....nothing. Is there any advantage to having this? Is there anything else to do? Just noticed I haven't provided required info. 2006 F250 6.0 liter 92,000 miles. Only upgrade is air raid air cleaner. Thanks for any help you can provide.

Get me your calid. Go to options -> troublshooting-> show calidbration ID.

I'm aware of the update you're referring to, it's one of the updates that basically reprograms the FICM and makes it impossible to get any power out of. We'll see what we can do though.

The calid is vxcf9h7.
