New Problem No Pull after 3,000 RPMs

[Hertz]

Quoting mikus:
a boost leak will cause an increase not a decrease in spool-up time



Perhaps, but he said he had full spool at 3000rpm.

Quoting NateCrisman:
Check your cam timing, a timing belt that has slipped one tooth can do this: good low end power, early spool up, and dog poop top end



Notwithstanding anything like timing belt itself, I would think insufficient fuel, or a vacuum leak at the FPR (possibly bad FPR solenoid), bad or mis-calibrated FPR, insufficient voltage at the fuel pump, clogged fuel screen or filter, etc.

Exhaust restriction?

BOV opening under boost? Vacuum/pressure leak?
