This is the sort of response I have right now, 14.7psi @ 2871rpm and 27.2psi @ 3250rpm...



I have bucket loads of midrange power and then it tails off to about 21psi by 6900rpm, such a drivable power curve that I dont really want to lose!
Although it doesnt spool quite so fast with this XR3i gearbox in as it did with the XR2 final drive ratio.
