Running the 4.65 pulley right now on a D1sc. And I have a 4.5 pulley sitting on my work bench. Wondering if I can just swap down one pulley and be ok without needing a retune? It'll be like 1 maybe 2 psi of boost and I'm barely seeing 11.5 to 12 by 7500 rpm with the current pulley. Figuring I can just data log to make sure everything looks ok as far as afr and knock. What do yall think?

My bad it's a 4.63.... yeah you can have it. They are 80 or so new so you think 40 is good with shipping?

I think you're nuts to swap pulleys without getting a tune to match. But that's just me.

I would get a revised tune.

A re-tune should be done with the installation of a different sized pulley!

Pulley changed... tune is fine, Not pulling timing, afrs still a little on the safe side, hitting 14lbs and pulling like a freight train. Didn't increase AITs by much at all or if any. I've seen a bunch of gts running the 4.38-4.13 pulley. So I don't see why a 4.5 will hurt a boss motor.
