• Power Gain:
• Without Port-Matching: The 95mm TB’s full potential is slightly restricted by the LT2’s smaller inlet (stock LT2 inlet is ~87-90mm).
• With Port-Matching: Adds 3-7 RWHP, 2-5 lb-ft over unported LT2 + 95mm TB. Gains focus on high-RPM (5,500-6,500 RPM), as the smoother transition maximizes TB flow.
• Dyno Evidence: LS1Tech and Texas Speed note 3-8 RWHP from port-matching on LT intakes, with smaller gains (3-5 RWHP) on already-ported setups (2020 posts).
Grok says 3-7hp in a typical FBO car. I was going to get my MSD ported in Houston and the only local person I would trust would be Greg Good.

Man, thanks for your input! Where does Grey work at?
