2015 3.5L ecoboost dead throttle

[DiabloMatt]

I've got a question for the team. Is it ok to run the 87 tune you gave me on 91 octane? Its been working great for the last 3 or 4 months and I thought I would try the 91 tune so I filled it with 91 and loaded the 91 tune and the dead pedal was back. I updated it before I installed the tune. But the 87 tune ROCKS. Very happy with it and thank you guys for that. My truck has hancook tires and they hookup great. Certain surfaces I can almost unload the front shocks at launch with the traction control. Makes me feel like a 19 year old kid in a 70 roadrunner all over
again. LOL

there are no more dead pedal issues unless you went throught the EZ tune menu. make sure tool is updated and go through the advance tune menu and the 91 tune will work

I'm thinking it's a pc issue. It's coming back to me now because I think I had to use my other pc and everything worked. Will try it Monday on a shorter workday and I'll have a little more time. Until then can I run my 87 tune on 91 octane with no issues?

correct... you will NOT have any issues using a 87 tune with 91 in the tank
