Quickie answers..

Wideband installed with a new sensor..

Aeromotive boost referenced FPR - base pressure is set to 45 psi with out the reference line installed.


I have a holley/walbro 255 sitting beside the 'puter, thanks for the offer. I'll pull the box deck off and change the pump maybe tomorrow.

I put 380 mile on the truck today going to the last big car show rod run around here, to bad a wizzy 63 GTR Vette parked beside me - but for the folks that did look - some of them got a sore neck from a double take.. \:\)


Oh ya... 65 to 100 MPH is like 3-4 second and thats backing off when the boost just really starts to happen ( no fuel), cruise at 80 MPH - 2200 rpm all day long. 100 mph is like 2800 rpm.. @ 1/2 psi, gee wonder what a full 8 psi is going to do..

My buddy that makes the turbo manifolds say my conversion to the dark side of boost is now complete.. its a wonderful thing.
