Now Idk if I should just buy a 4.13” pulley or not. PC says I’m not gonna see 7psi until 7k rpm….ugh!!!!

Probably difference in exhaust and intake manifold. but I would just use the smaller pulley and lower the shift rpm. My friend's car only made like 7psi @ 6100rpm and 3psi at 4500 rpm. So a larger pulley is just going to take longer to make boost and reduce power under the curve.
Here is a couple vids.
1st vid is a Heads Cam converter 4th gen on a 180shot, the P1x 6th gen, and My Whipple 6th gen. I gave the hit to both cars.
Second run is 4th gen vs my 6th gen hitting at the same time.
Both 6th gens are similar boost. I make like a half pound more peak but quite a bit more under the curve. I am on E40 he is on 93. All 3 cars tuned by me. 4th gen trans doesn't like the Nitrous through the shift. Just posting this for comparison on how much difference giving up the hit makes.
Either way I suggest doing what it takes to continue running E or a blend of because 93 and boost is leaving a lot on the table.
