If so, what size should I go to, as I mainly want to reduce lag, and get a better daily drive on E85, rarely using pump fuel.

Changing the gasket won't help to improve spool. Increasing compression just squishes the same amount of air more. It might help a little to improve out of boost drive ability, but not that noticeably moving from somewhere around 8.8:1 with the 1.5mm to 9:1 with the 1.2

Yeah, I was hoping it would shift my power left. But I might just leave it a put on a supercharge to help spool

LOL
Here's a graph of my power, heaps of lag.

^Ouch. That's what an HKS 2.3L and Blouch bb 80R produces? I see people on here having far better luck with stock block fp black setups.

Yeah, finally gave up on the Blouch and went with a locally made turbo GTP762. This is my track tune, getting full boost and stock power around 3750rpm. Street tune is at 32psi making about 370kw's
