Increasing the compression gained 1mph.

I know the engine can rev much higher than this, because it revs much higher when the car is sitting on a work stand. Of course there's almost no load on the engine then. At this point I'll have to wait for warm weather and an opportunity to drive it for an extended period of time, so I can really tune it properly. I leaned-out the HSN by almost a quarter of a turn today and it was still blowing smoke, so it's nowhere near lean. Maybe all the extra power is waiting for a proper tune before it will show itself. I *have* made a bunch of changes that ought to require re-tuning, after all.
