Dont think its a voltage thing. Im back to 2 battires now.

Fuel pressure in high gear is around 6 61/4. But it dont now what fuel pressure is off the line?

Im going to cut 2 holes in the front of the cowl to let some air in. Its a piece of trash in high gear. Runs less MPH than it did before, but the 60' is best 1/8 mph is up some an 1/8 et is getting better. This should fell like afterburners kicking in!
