Nope 1 to 2 psi with the size engine you have won't work. You would have to extremely lean, above 40:1. Now this is based on the 4 to 6 hp needed.
Sorry but its the truth. To make your engine cylinder deactivation would take a crazy amount of change.
Keep in mind the engine is just a air pump. So when you increase your air flow
you can only do so much with lean burn and higher IAT to keep from having to add extra fuel. This becomes even more of a issue because now you want a low HP output from the cars aero improvement.

I was afraid that cylinder deactivation would be a more involved process than just cutting off injectors. DOH!
Maybe I should take 2 cylinders out and be done with it
20:1-25:1 is well within the reach of tuning software. It looks like I'll be heading down that road eventually.
Hmmm, I'm trying to think of a way to decrease the amount of air that the engine will get in my usual rpm range. The only way I can think of is retarding the intake camshaft and creating an Atkinson Cycle. Thoughts?
