Honestly, it's so much better like I have no issues with any of the above. Dare I say it I did go to a smaller throttle body as well, so weather its one or the other or a combination of both I couldn't say. But I can say I think it definitely feels much better and drives much better, but yeah, I'd say calibration / setting up and tuning it properly plays a big part too. The guys who done this for me have done a great job. I can honestly say at this point it is much better that it previously was with the 80mm throttle body and cable throttle. As for people saying its slow, I'm guessing it's the kind of people who think they can do things better and faster than a computer maybe lol.
