I've been told it might take a little while before you feel any differences - I've heard maybe about 200 miles of driving. But it might vary based on driving conditions. I also had concerns about the dealer installing the tune. Rather than them downloading the tune and installing it I...

Follow up from an earlier post of mine back on 4/26/2019 regarding getting ping after the FP tune install. I currently have about 14,000 miles on the car. First oil chance was at 7,500. Second oil change at about 13,500. I tried various types of gas and finalized on using Shell. The ping...

And yes, I just re-read the instruction, and it seems you are correct.

Yeah, Ford Performance also said colder plugs shouldn't be necessary (though, surprisingly the dealer recommended colder plugs with the tune). Yes, I'm using full synthetic - Amsoil (though I'll probably go with Mobile 1 next time around until the new oil standard is available). I can only...

I'm guessing at 91 octane the tune is right at the edge. And using Shell, the knock is not bad, but it's still there from time-to-time, and I'd like to try to get rid of it if I can. And the octane adjust option is just on or off to use different timing tables for what is even a slightly less...

I've tried a couple different stations. My latest was Shell, and the knock - when it occurs - isn't that bad compared to some others I've tried. But it still happens. I can get 100 octane racing fuel here, but it's $8/gallon, and it isn't a top-tier fuel. I've considered mixing maybe 3...

Sorry, I should have been more clear. The Pro Cal software won't allow me to enable Octane Adjust. I didn't try the diagnostic tab. Maybe I'll give that a go. But even if it's not throwing any codes, a knock in a high compression turbo engine makes me uneasy. I suspect 91 octane being the...

Unfortunately, I have no idea. You may want to contact Ford Performance and ask them that question. BUT, I do have a question for you. Did you notice if the Octane Adjust option was enabled? I have periodic pinging issues. When I tried to reflash to select the Octane Adjust option, the...

Could be low speed pre-ignition, which may or may not have anything to do with the tune. Your situation sounds like that may be the case - low speed, high-load.

Here in Las Vegas the temps have been 105 - 110 degrees. So any drag mode impressions would probably be tainted. Even so, when I tried drag mode a few weeks ago the car chirps the tires when shifting, but the car did that even before the tune. I don't have any before/after 0-60 times. On a...

I need to agree with Cxp. It's a different car. Quite frankly, if it had any more power I don't think you could take advantage of it anywhere other than the track without getting in trouble too quickly. I think it's the perfect power for having fun on the street. And while this is considered...

Yes, I noticed the smoother shifting transmission as well. I also wonder if there was some fiddling with the traction control. With the added power there *appears* to be some added traction. But this is total speculation on my part. And yes, I mentioned in a prior post that at 45 when I...

91 octane all the time since I bought the car.

Yeah. Fingers crossed. I'll post as I get additional info.

Had my tune put in yesterday. Didn't feel anything at first. I knew there was a learning period, so I put about 50 miles on the car and am now starting to feel it. I was doing about 40 mph in sport+ mode, floored it, and chirped the tires. That never happened before in sport+ mode. There...

Just had mine done yesterday. Bought the pack for $425 on-line. I asked my local dealership how much for install. I was told about $150, which I thought was cool enough. I had already downloaded the tune and put it on a flash drive for them. They come back in an hour and say it's all done...
