Ive been searching old links for some input but no luck. Last weekend I got a predator and banks exhaust. Exhaust on ,programmed 65 hp tune ,recalculated tire size and was amazed to say the least. So im due for service and loaded stock tune back in.(just like the manual said) get home today from the dealership and loaded the 65 tune back in. Everything went perfect but the power doesnt feel like before?? Its almost as if it is the stock tune. What gives? Also the manual isnt very clear, when I try other power levels do I need to do the tire size thing in each setting? Thanks:confused:
