For those of you trying out different tunes, do you return to stock before loading a new tune? I recently switched from an LET tune to a 5 Star just to analyze the difference when towing. Just driving around town, the 5 Star doesn't feel the same as the first time I had loaded it. Admittedly, I do have 10 lb heavier tires now, but I was wondering if it would be a good practice to return the tune to stock in between custom tunes.

I used to not to, but now I do unless it's from the same tuner.

It's a good idea to return to stock Lee. PM me later if you want. I have some info on that. It's also a good idea to do the battery disconnect every once in a while.

I do not return to stock I go from tune to tune. Never had a problem.
An SSI tune did wonky things to my cruise control. I switched tune-other tune and still had the issue. Switched to stock and then other tune, no problems. So there can be a difference.

Like I said I have never had a problem. And I know I have tried more tunes than anyone on here.

I go to stock about every 3 or 4 tunes if it's the same tuner.

I always go back to stock if I go from one tuner to another.

It's also I good idea to return stock just to make sure your device software is updated as well. Specially with all these changes they doing on the x4 and Livewire.

It's just what I do and has always worked for me. I'm not saying it has to be done this way.

That's a mighty BIG ASSumption Tex.....

Some of us have been running tunes in multiple vehicles literally for decades now. The BASIC principals of ECU flashing (on most common vehicles) are pretty much the same.
