Why do we have to sacrifice fuel mileage for hp? I have yet to here anyone on here that didn't say they're gas milage suffered after they installed a programmer or/and aftermaket exhaust. I had both on my 636 and suffered no gas milage what so ever. And the power commander made it come alive. I am at the point that i'd like to get some pipes but I can't do it if its going to cut into my fuel economy. I have to stop and get gas often enough as it is.
