I've made ZR 800 EFI -03 based turbo sled. Built it last winter and it ran nice until last rides at spring it had some hickup: wont rev more than 6000rpm anymore. It's like rev limiter limiting top part out. Sled starts and run normally at 0..6000 rpm range.

What can cause this? I've tried another ECU and that small wire harness (for all sensors, tbody etc) which attach into ECU. No ecu error codes either case. Could it be voltage regulator as APV get the power from there?
