Hello. It's been a while. I recently installed a cam, intake and long tubes in my truck (95 K2500 454). It runs amazing after a little tuning and now I want more of course. I've been sitting on a 4bbl TBI for a couple years and I want to install it. Aside from 1000 other complications I can't find the BPW constant for this bin anwhere in TunerPro. Or maybe I'm looking for the wrong thing? Most of my experience has been with the 7747 $42 mask and the EBL.
Here's a pic of the throttle body. I'm kinda proud of it. A friend and I spent a weekend making it
