For one I would not run a 12:1 fmu. My reason is that you max out your stock injector0 at bout 90 or so. Ok stock fuel psi with out vaccume is 43.5 psi. Ok so at 10 psi your fuel psi would be 163.5 psi of fuel. Ok that is way to much psi for your injectors to even think about trying to control. Befor you go with that figure out what you really need. To make this shorter I will skip all the fourmals. At 9 psi of fuel with stock injectors (235cc) you would want around 123 psi of fuel. Thats alot of fuel psi for the injectors to handle. thats why i got the 450s. yes i have the resitor pack. with out it you wont run verry long befor destroying the injectors or maybe you computer. so for the 450s you would want around 30 psi at idle and 40 psi at 9 psi of boost. but to run the 450s you would want a S-AFC for idle control.
