Yes… it was my engine . We did around 7 power pulls but spent quite a while doing low rpm/ part throttle tuning .
This guy was exceptional though… he had my engine for 3 days. Day 1 he hooked it up, Day 2 he broke it in and did some baseline tuning , day 3 we did part throttle and wide open runs for 6 hrs.
He charged me $650 if I recall .
