It's a totally different beast now. Snappy as fook. Exhaust note is totally different, engine seems to have lost a little bit of bottom end but wants to spin like a top.
Must be because of the increase in rocker ratio increasing lift, valve opening and closing speeds and 50thou duration. Bigger valves, increased compression and ported lower intake obviously contributing too.
Off to the dyno next week for a before and after comparison. Then once I figure out Quarterhorse and get it tuned properly then a final dyno reading. The poor old
ECU doesn't know WTF has happened!
