I know how it sounds... I'll have it back on the Dyno in a few weeks. I'll have to get a video and pics of it. I had it street tuned and when we did the first pass on Dyno it made 383, 423, 460, then 483, 501, 523 and kept climbing on pump gas. My tuner said he want to hit 550+. he claims he might be able to push 600+ out of them... so I'm holding him to it. We'll see. He is GOOD! Others Ive seen tune this motor on stock twins have pushed 350-375whp with similar set up but with AEM. I have the Microtech, which to date I feel has been one of the best investment made on this swap.
