7427 $31 BPW constant address?

[V8Astro]

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

The 7427 has an actual Injector Flow parameter and a Displacement parameter, instead of BPW.

Nice work on the 4 BBL!

Thanks! I'll have to look for that

Ok I found them. The VE table only accepts numbers up to 100. If I needed to add more fuel would it be better to raise fuel pressure or fudge one of the "inj flow rate" or "cyl volume"? In the past I would have raised the BPW by a percentage then lowered the VE table by the same percentage to get the numbers less than 100.

If you need to add more fuel I think it's better to "decrease" the "injector flow rate in one lb increments" to achieve VE numbers less than 100.
