I have a 03 SO. I have a intake, exhaust, and the EZ. I am getting the Juice w/att. soon. Do I need to upgrade to a FASS system or something similar? What is recommended? I am not doing twins or nothing major like that. I probably wont go much further than the Juice. Dont want to fry the tranny yet. I was looking on a site and reading about the FASS and they have different ones. What do I need? Also, I will be doing some towing on the weekends. A enclosed race car trailer. Thanks for any help.

 

You should upgrade to a different fuel pump. 03's still have the fuel pump mounted on the back of the fuel filter and suck for flow. A FASS or the like should give you a few more HP and a smoother running engine

 

I have a Walbro on mine. I have the same yr/engine and it supports 490 hp.
