I was talking to the folks at straightline when I ordered my exhaust. They were saying that the newer ITC throttled rigs don't need fuel programmers or need the ecu's flashed, saying the new fuel mapping is better. Anyone have any thoughts on this? I was going to get it tuned but if I can save the cash I will. I'm not a hard core rider but do like like toys to run their best. I have a vmax motorcycle that I had dyno tuned (same guy that was going to do my outlander) but on that I replaced the full system including the cats. FYI, he was able to squeak 200HP out at the rear wheel.
