The rest of the way up the revs boost wanders between mid to high 190's. It was a tuning run that I thought was good enough to post. I've added a bit of fuel, and I might bump up my boost offsets just a hair. And of course this run was performed on a private closed course.

in the middle of tuning with a new fuel pump. max boost is currently 11.5. I used to have a 14lb WG can and boost came on earlier, but I like having more adjustability even if it blows open the door and sacrifices spool down low. making more boost at lower rpm doesn't seem to make any difference in torque. it comes on pretty strong between 3500 and 4000rpm though.

Right above the 7.25 psi the wastegate starts to open, so in the log boost tapers off. I'm out of town until sunday, but when I get back I might readjust the wastegate to get some data up to about 10 psi.

Spools like a 2560R on a '99 head, except it's on a '94 head and the tune is so rich I could smell fuel vapors in the car after doing long pulls.

lets see what happens when you start at 2k instead\as well

I fixed a loose wastegate and ohmygod I can hit 15 psi at 3000 RPM. (GT2560, VVT head) Official data later.
