There is an optimal tune for MPG's,.. and a different one for HP,... and yet a different one for street performance... and another one to meet EPA emission and noise regulations...
An open pipe would make max HP at full throttle and be good for drag racing with a high rev launch, but it would barely idle...
A certain amount of tuning will remove EPA restrictions, and make the bike breathe better... without hurting MPG's or narrowing torque... all you are doing is correcting factory restrictions... Even with a bigger jet,... if you are making the engine more efficient by removing restrictions only intended to reduce noise and emissions, you can get better MPG and power... You will just use less throttle at a given speed... If you start to go further... you will begin trading MPG for power, and HP for torqueband width...
You tune for how you ride... most of us, like stop and go, and curves and hills... so we tend to recommend mild changes that will retain good torque... Thumpers do well in that environment...
