Indeed you did mate, it'll pick up a couple just minus the airbox and back to the known good settings, making your 55bhp prediction all the closer, I might even get passed it
From the richness "wiggles" on the graph you'd say there was a good 2 horse there, then maybe one more in losing the airbox, 57-58, normal fair for a '28 isn't it?

I'll just have to try harder, that shouldn't be tough
