I have a Stillen stage 4. Going to throw out the canned tune for a pro tune. I have DW 600cc injectors laying around and a walbro 255. Will I need a fuel return with this setup? (I know 600cc is overkill but they are free)

Also does anyone know where I can get a custom pulley to add slightly more boost than what stillen pulleys offer?

I'm aware of the shortcomings with this sc but I got such a deal it was almost given to me. I tried to research this on my own but hit a brick wall. Thanks for any advice.

 

You should get a fuel return system especially when going larger injectors. Not for more fuel (in this case) but it makes tuning so much easier when you can adjust fuel pressure and it will be better maintained by the FPR.

 

Thank you! I'm clueless when it comes to the fuel system.

 

Anyone else have any input?

 

You don't need a RFS for 400whp & 600cc injectors.
