5 is very helpful for driveability as Bill mentioned. Intake will do a little, exhaust a bit more but nothing wild. I'm sure you are aware of the potential and costly optispark issues correct?
Btw, stock shifter was fine in the car but the Hurst is noticeable better. I'd probably sell my Hurst plus with Lou's short stick for a song since I've switched shifters.
