Try different ones and see what your rail pressure is at for each...But if i only go with the smarty?
Yep... doesn't change whether I turn it off or on. Still at 32max now.
Used to get 40 on the old tune.
Starting to make more sense now. I may stick with the revo instead of the TNT. I tow heavy so it may be best to stay with the lower tune. Last time I crossed the scales I was right at 25k so I may need to leave it on the calm side.i dunno i never downloaded the revo i just went straight for the tnt! with the tnt i can get 39 and like you said use to be able to get 42!
