That almost sounds like the truck is not back to stock tune wise. I would double check.

It is, because when I go back to plug in the tuner, it asks what level 1, 2, 3 or 4 and stock isn't an option.
It's stock tuning, I can definitely feel the transmission shifting difference along with the obvious power decline.

Diablo's ask what Octane tune you want to install, the return to stock option is under restore vehicle. From what you are describing the truck does have the stock tune, but as written by the programmer. If you restore vehicle, then the tune is truly removed from the truck and it is back to stock.

I had an H&S Mini Maxx and had KEM put a tune on it for me. The tuner had to be sent to H&S to get the firmware installed on the tuner so it would be compatible with the Ecoboost. Probably wasn't the best option but since I already had the H&S from my old Diesel, I figured what the heck. I do love all the monitoring that tuner gives me. I still use it to monitor exhaust temp and boost levels.
When the tune is installed, truck runs fine. I just am iffy installing the tune back on it since the Ford dealer can now not flash my PCM for some reason?? I guess it doesn't really matter at this point, but I'm worried that my PCM might fry or something if I try installing it again. Truck runs okay with the stock tune now, I only ran an 87 octane tow tune because I mainly wanted just better shifting instead of power.

Do you realize that this is a thread about Diablosport Tuners? Your first post made it seem like you were calling out diablosport being detectable at the dealer, That is not the case as you do not have a Diablosport Tuner.

In regards to your particular issue with the H&S, the tuner has not been restored properly, that is why you are having issues with reflashing the PCM. Take it back to whoever installed it and have them remove it.

I do realize that, however the guy at the Ford dealership says he has seen this issue several times due to tuners being installed. Luckily he is a good friend of mine and just let me know just in case I had to take it anywhere else.

My inquiry here was if I bought a Diablosport tuner will I be able to flash if Ford wasn't able to. My minimax tuner can install a tune and put it back stock, but for some reason when it is "stock" Ford can't flash my truck. I asked them to fix it but with the ongoing issues with the EPA and H&S, they will not do anything. At least that's what they told me. This is why I'm looking at getting another tuner possibly because KEM said he will not be able to install tunes on it anymore due to H&S dropping the firmware or something like that due to lawsuits. My truck is back to "stock" but I'm worried that if I bought another tuner it would give me an error.
I'm looking to sell my H&S MiniMax to a buddy of mine that has a diesel. H&S will install firmware back on it to make it work for a diesel but will not do anything for a gas truck. At least this is my understanding.

If it is back to stock I don't see why you would not be able to install another tuner. We do it on a daily basis. If you attempt to install another tune and it complains about programming, then it is not back to stock.

The other possibility is that the Ford Tech was lost, because we have an IDS in house and we can and have re-flashed over every tuner on the market without issue.

I'm interested in this for my 2015. What's the difference between the regular Intune and the I2? I've run the Intune DCX on my prior Rams and liked the performance gains. This truly is untraceable? Thanks in advance!

The Intune has since been discontinued. The I2 is the newer version of the Intune. It has a better screen, more powerful processor, it is wifi updateable, amoung other upgrades to the device.

At the dealer level the Intune and I2 cannot be traced.

How many engines have thrown rods using a SSI tune? And the crappy customer service? Almost anything would be better.

The Diablosport looks good.
