I decided on my Z06 I wanted to log when hp was falling off to determine my optimum shift point after the cam swap. I'm thinking I want to do the same before the swap as well, I'd love to see the airflow curve before and after. So I figured out how to make a PID that would spit out hp. GM already calculates delivered engine torque. Who cares if it's accurate or not, all I need to know is how fast it's rising and falling to see where the optimum shift points are. I've been using V7.5, but custom PIDs look like witchcraft so I cracked into the V8 software I'd been avoiding using because I didn't feel like remaking all my histograms (which is super easy BTW). As suspected, V8 is a bit more user friendly once you get to know it. The custom PIDs don't require you to have a programming cert. But I was having connectivity issues with the Z06, so I said screw it let's try it on the truck and it worked so I went out for a rip and this is what I got on a 1-2 shift.

I told myself the numbers didn't matter until it claimed it was cranking out 440# of torque and 362hp here at altitude. Who knows how optimistic those are. Torque peaked from 2800-3400 RPM and HP at 5250. I was commanding a 5200 shift, got a 5300 shift. I'd monkeyed around with that a bit end of last year and kept over/undershooting my target no matter what I did with the mph and RPM points. I'd had the limiter set then at 5400 and would occasionally bounce off of it. I bumped it by 200 up to 5400, we'll see if it shifts there or closer to 5500 and also how the hp is falling off up there. I'm curious
@L31MaxExpress didn't you run the Ramjet cam with marine intake on a 350 at one point? Curious where yours wanted to be shifted at. Of course the blower could be artificially stringing this along too.
