Non ZR-1 Dyno graph help - ZR-1 Net Registry Forums

limey · 04-22-2009

I took this car to the dyno yesterday and am having issues with it dropping power @ 6000 RPM, in both NA & on 5 lbs boost.

Any ideas what would cause the car to drop and then re-gain power at these levels? I have plenty of fuel & the car doesn't have knock sensors, as per factory.

Just looking for some other opinions on where to look, what is the key i think it it does it both NA & Boosted.
