I was pretty pleased. I'll post the graphs later, but here are my results. All on the same dyno. Car is a 2022 SS 1LE.
1. RotoFab CAI and Corsa NPP axle back were my initial mods. First dyno run - 412hp, 458tq.
2. Added MSD Intake (non-ported) and Soler 95mm throttle body. No tune. 428hp, 446tq.
3. Today I got a tune and ended up with 448hp, 433tq.
That's a 36hp (9%) increase. 25tq (5%) decrease.

Nice numbers man. I currently have a LT2 intake manifold, ZR1 95mm throttle body, rotofab cold air intake, speed engineering 2 inch long tubes with their 3 inch catback connected to the stock muffler and E85. Also has almost the entire bmr suspension catalog. Running 305s on rear and 245s on front.
My car dyno’d at 450 Rwhp and 480 torques, when you get long tubes your torque should go back up.
Every dyno and every engine are different so don’t take these numbers too serious, the way the car performs is what counts. Smiles per gallon.
