fuel ration to run 2.87 pulley on V2 s/c'r ???
 

I'm currently running a 6:1 vortech fmu for the 3.125 pulley on the V2 s/c kit. I was wondering, if I upgraded to the 2.87 pulley will I need to change anything.... BTW, The car is controlled by the Apexi S-AFC controller.

Run 370cc injectors and use the S-AFC to control them.

how much horse power/PSI will u have when u put in the 2.87 pulley
thanks in advance :D

~12.5:1 AFR

Test and tune it on a dyno with a wide band O2 sensor to be sure you have it right.

My advice to you is an 8:1 FMU disc, it will be rich but you can lean it out with the AFC. This is the safest approach.

doesnt the ecu adjust to the s-afc over time? negating the benifits of the s-afc?

If you set it up properly, no.
