I would personally pay that much money only to fix up the throttle delay, as I find it very annoying when I try to heel and toe. But I'm not surprised the power gain is very modest.
Thanks for understanding my review and you're welcome for it. There have been dyno sheets that've showed gains from the tune, but 10-15 HP is minimal, as are any gains from any performance mods to our engines. I just want people to know that I personally didn't feel a significant difference, but there's definitely one -- just not one that will blow your mind.
