Default S2000 throttle issues post dyno tune

I don't really know how to word this, but basically after getting dyno tuned on my 2006 S2000 with Hondata flashpro, the throttle response has been very slow. I have a lightweight flywheel and it used to rev up quickly, and I used to be relaxed between upshifts. Now after the tune, I have to blip the throttle very hard for it rev up for downshifts, and I also have to shift quickly for upshifts, or else the RPMs return to idle quickly, and I have to shift even quicker with the AC on.

I was told this was something to do with the DBW/throttle plate? How can i get the stock rev hang back while keeping my tune?

I have my tune saved, and was wondering if anyone knew someone who could help me?

You're describing the effects of a lightweight flywheel -- less flywheel effect. The OEM flywheel is designed and exists to prevent what you're experiencing.

Reload the OEM tune. Same effect?

I recall there's something in the late cars to delay the clutch (or maybe I dreamed this?). Your tuner is your best source. Mine was done by Gernby but I have the OEM flywheel and have yet to see any advantage in a non-OEM flywheel.

Regardless of flywheel it affected the rev hang. Yes I have a lighter ap1 flywheel, but my point is now it feels like I have a 100lb fly wheel if I could describe. And yes it's something affected by the tune because when I go back to stock it revs freely again.

I emailed gernby but he didn't reply idk if I have the right email
