I understand all motors are different. I will try to ask the question best I can. Im going for tuning on March 5th. I see my biggest limitation as my rc 440's. My question is this: is x amount of power at 80% duty a semi-standard amount? In other words, will a 3in dp and exhaust make more power @ 80% than the same car w/ a 2.5in dp and exhaust? Is the 80% the limiting factor or is the x amount of power the 440's can support. Understand?
