I bought my car with this set up,

-Trick Flow ported heads
-Comp camshaft
-Harland sharpe roller rockers
-Fast 90mm intake manifold ported
-Nick Williams 90mm throttle body
-SLP air intake
-Slp under drive pulley
-RK t56 built transmission
-Kooks true duel with 1 7/8 headers and full 3in exhaust no cats
-New motor and tran urethane mounts

If were to switch over to a Fast 102mm and TB would I see a difference with a new tune?

Ported 90 to a stock 102?

Correct

No gain then. In fact the 90 will probably have more power if it's ported right

You MAY see a small gain up to 5hp, but it will be in your upper rpms only, not across the entire range.

It's not worth it if the 90 is already ported well. Keep the 90.

i would make the switch and have the 102 ported to match your heads.

Not worth the trouble. Ive had both intakes.
