Changed 58mm for 48mm, raised fuel from 44-47psi and put on Ram Air

[UB2 SLOW]

Congrats Man. I know I noticed a huge difference when I went back to a 48mm. I have since upgaded to a 52mm and I can really feel it. The 58mm just had too much air. I know have the Ram Air also. Good luck with that car. I bet it is a monster.
