Thanks for the complements. The reason I ran pipe reference was because when at lower rpm when the turbo isn't charging the system and it doesnt give the fuel regulator a pressure. It could/does develop a lean spot because the fuel pressure regulator isn't working properly compared to the rest of the system. With the pipe reference it always has a pressure making the fuel regulator work all the time. My issue started when I had a low end bog because of too much fuel. I was going to drop my pilot jets to a 15 (and still might) but because I already had taped and plugged the intake for another reference I just tried it from the intake with the 17.5s. I do not have the bog on the bottom end anymore. I also did the pipe reference because originally I was going to run low boost (3-5#). After I got the addiction I ran my boost controller to my intake and am running 9-11#. This season in CA was really bad. The usual spots never got snow and I finally got my clutching and jetting dialed at the end of the season. I will have to say that I hardly have any boost lag and it is very mean on top end. It took me pretty much all year to get it dialed and can't wait for next season.
Set up running 50/50 91/110....
Jetting
350 mains
17.5 pilots
No shims under needle
.20 gapped plugs
Clutching
160-260 primary spring
413 ramps
No pin weight
66-62 .33 team tied helix
120-220 secondary spring
I like running no or low pin weight because it is easier on rollers, buttons, and ramps. It's like running a 200-300 spring with 16 grams of pin weight.
