Yes I had -1 degree for every PSIA over 15. Would retard so far engine would bog.

Took all retarding out of cells. Car took off and boosted fine.

Almost thinking vvt is fighting the map

" Yes you had it -1 degree for every psi over 15 psi? "

You're telling me until 15 psi you're running 30 degrees of (final) timing?

Ah absolute psi, never heard of that term but cool. Well 10 degrees vs stock puts u at 20 degrees at 10 psi. Most people run about 16-17. Anyways u cant be driving with no timing control so figure that out.

Wait so now you're running a boosted VVT motor on factory timing maps?

Well technically he is right. For some the learning process is more expensive than for others.

42 should be ok for 1-2 psi. Probably will get blowout at over 5 psi though.
