Well, kinda! It seems to have moved the torque from not so low down to more spread out over mid range. It's a lot more smoother through the range.
Not to mention it powers on now to the 7k rpm range.
I can't say throttle response is any difference, if anything it takes a split second longer for the torque to kick in. But all engines are different and tuned differently.
I am happy either way, and mark did a great job.
