yeah, i've been looking and looking. i did find that its 10:1 compression but thats it so far. i like to run a little leaner for my light boost. with the compound setup it should spool way faster and i'd like to see how lean i can go in those light throttle hill climbs and what not.
it seems to me that if you can run lean cruise mode that goes to 15+ then why not be able to lean boost in very light load situations.

just thinking out loud.....

they go rich, under a few WOT runs in one at work you can smell the cats from the excess fuel

But I'm talking non wot runs. Like part throttle towing type boost. Or just part throttle hill climbs. Most new cars go rich now days when they go into cat over heat protection mode.

I will run at 14.7 up to 5 psi at part throttle with no issues. The EGT will climb fast but not any hotter than a WOT blast.

I think mine is setup to go 12.5 at 2000 in boost..

know a couple people around here that have the EB and they say it gets great gas mileage just cruising around, but hook a decent trailer to it and it goes single digits.
