SCT Livewire tuning question - Swapping tunes

I have Gearhead custom tunes on my SCT Livewire, DPF deleted, and was curious if I have to return my truck to stock before swapping from like a tow tune to a street or hot street tune?

Also in regards to the tranny learning shift points etc, how long are people letting their trucks run in a tune to relearn all that? I tow about 2 weekends a month and would like to be able to run street or hot street tunes but don't want to have my truck relearning the transmission shifts every other week in the summers if possible.

I guess I never thought about this with my 6.0 and just had it brought up from another member on here who has a different tuner and thought I should post up for a good answer.

FWIW I usually would load a tow tune on my 6.0 and tow basically the next day. Never really thought twice about it. I did that last weekend with my 6.4 and didn't think about anything being learned or changed and needing time to learn.

I always returned my 6.0 to stock tune before going from tow to street, but am not curious if that is necessary.

Thanks

I wouldn't say that its right or wrong but I hook up my 35' deck over and switch tunes from Hot Street to tow while I'm loading 2 35hp 4x4 tractors with 5' brush hogs then I just drive like I got sense. I've personally never had problems and I do this sometime 4 or 5 weekends in a row in the spring and summer. Also I never go back to stock in between tunes and usually never go to the street tune (I shouldn't have started with the Hot Street)LOL.

You do not have to load the stock tune, just swap from any tune to the tune you want to run. You don't have to worry about letting it learn before you tow, just load it and go. I run Gearhead race all the time even when towing but you have to pull with common sense.

AWesome thanks guys, since going to the stock tune takes so long I was hoping this was the case. With my old SCT tuner on my 6.0 I did have to, but it took about 1/4 the time.

Definitely looking forward to running the hot street tune now that I know it's a lot easier and quicker.

Thanks!

Switching between custom and custom, you do not need to return to stock, switching from preloaded to custom, you also do not need to return to stock. I have never went from a custom to preloaded without returning to stock though since Eric has always told me to return to stock before loading preloaded

Just tuned from Tow to Street, I wanted to not step right up to hot street in fear I would never want to tow or use anything else. Didn't go to stock or anything and truck fired right up. Actually when it fired up I could tell right away it was different, not as deep of a tone and seemed to be running almost "lighter" if you will.

Looking forward to driving with that for a few weeks, then towing, then thinking hot street. Thanks for everyones help.
