Yeh, EQ heads without guides are a pretty risky proposition.
Looking at the fuel flow disparity between A & B, it would appear a weaker secondary spring might yield a few extra ponies.
The secondaries a don’t look to be open enough to contribute anything till after 4k.
Yes, I will definitely be heading back to the dyno after the repair. We were just getting to the fun part lol. Glad the valve hung up at idle or things likely could be going a totally different direction.
Getting more timing and the secondaries sorted out was what we were about to get into. All my pulls were only at 34 degrees. Hopefully have some more refined results next time!
