[QUOTE="WHY NOT, post: 1404214, member: 1397"] I only put mine in tow tune when I will be towing heavy, otherwise I just leave the performance tune on. Only reason I tune it down is because I have drained the fuel rails on my truck before on the hot tune when towing causing the truck to shut down, but you shouldn't have that problem as the 15's have a bigger pump. If you get something like the ******* with the shift on the fly SOTF you can just click it down real quick when needed to make it safer [/QUOTE]
