what psi? when do you see full boost?

look at the map in 2d graphs, its pretty uneven and tapers off in the upper RPMs. your fuel values actually go down when you are near redline

no

here's how i start a vtec tune:

turn vtec off in your editor. now tune the boost portion of the map well above where you are going to have vtec engage. get it pretty close to where you want your AFRs

now enable vtec, but make it activate at like 3000rpm. tune your vtec map all the way to redline pretty close to where you want your actual AFRs.

now set vtec to the stock engagement rpm and do a pull. if you are on a dyno, there will be a decent dip in power once vtec engages. tune your high cam map at that point, adding or pulling fuel until the dip is as close to smooth as you can get.

fine tune from there
