Ecutek supercharged 1st drive can't get to redline

ZStalker505 · 02-18-2023, 09:12 PM

Hey all, I finally got to take out my new to me heavily moded Z and I don't understand why it seems like it cuts out or hits a rev limiter around 5200 rpms? 2nd 3rd gear doesn't seem to matter. Is there a failsafe that cuts it or what am I missing? This is all new to me.. car was tuned in FL it's now at a 5400ft elevation. Ethanol gauge is right about 36% don't know how old the fuel in it is, has a water meth kit don't know how long the juice has been in it either. I emailed the guy that supposedly tuned it and never got a reply been about a week.

I did two data logs driving around but that doesn't do much good if no one can analyze them.

Most likely some safety, lean or boost cut.
