First 700whp tune.

Kurt, you know I like you, but 690 on a single walbro even at 13:1, holy fuck. That second pump had to be working to NOT lean out more than 13:1 at 42psi. When I kill a single walbro it goes lean and lean in a hurry and I’ve yet to go that much north of 30psi. I can see 700 wheel with a boost a pump, you sure those guys weren’t using that?
