well if you are worried, just order over the phone, let them know your situation and see what they say, but you shouldn't have a problem. A tune doesn't actually just give a specific amount of fuel for the amount of air coming in. The MAFS can take densities into account from temperature etc, and the tune changes it that way. So an aftermarket tune should be close to as versatile as the stock tune. Since the stock tune is far less agressive, it will still be a bit more flexible, but i really wouldn't worry.

 

for all you out thereconfused by "MAFS", it means mass air flow sensor

 

oh haha yea sorry forgot to include that, thanks.

 

i live in minnesota so -40 to 110 and brenspeed told me the tunes will be the same no matter what temp, nothing changes in them
