Stock Trinity TVS, 10% lower, 2.5 upper

[RBB]

I know these questions have been beat to death, but how much boost are you 13/14 guys seeing with a 2.5” upper and a 10% lower on a stock TVS blower?

I’m running this setup with JDM cams, LTs/off-road X, and a cut and ported lower intake manifold (good for another 1-1.5 lb boost drop). Thinking I should see no more than 16-17 lbs here.

I think you're in the ballpark of your expectation. You're going to need to install a boost gauge to see where you really are. I think those cams are going to drop a lot of boost.

Everything I’ve seen says 2-3 psi for these cams. I’ve got a boost gauge installed....if it warms up a little and quits raining and snowing I’ll be able to get it out on the street and take a peek before I hit the dyno.
