I would call TnT, and ask them...They should be able to help you.

I had a compucar plate for awhile. I had to grind down on the TPS motor housing on the bottom of the TB and the thermostat neck for the waterpump.

Not sure about the plate but you'll need to bore out the intake to 58mm for the TB.

I deleted the iac. drilled and tapped the holes underneath the t/b. the idle is fine, and the engine revs up and down like a carb'ed car.
