Intake doesn't matter.
4.2" pulley only exists on SSM90 kits; which blow.
L26 is a turd and can't hold any power.
Sorry about the ZZP canned PCM.
Sorry you also didn't go to Triple Edge for your transmission.
I suggest more research on your end. It helps tons.
With a stock pulley (3.8"), headers, and your other misc. business like thermo and plugs/wires should be fine.
The problem is getting a solid dialed in tune. Canned top swap tunes ain't gonna cut it. There are plenty of people in Wiscansen that can tune.
