Incident form 4 years ago - still need closure

1995 Accord LX NON-VTEC with a 2001 VTEC Accord motor swap F23A1

Engine Never revved past 4k RPM

Was that simply because VTEC wasn't ran (VTEC ECU - WIRED to VTEC Solenoid etc.)

or was some other issue prevalent?

I was told that even without the ECU that the engine should've still revved like normal without restrictions.
