I think if the ecu freaks out with the boost i am going to throw at it then i will step up the injectors and run a good piggyback fuel controller to fix the problem. Caliculations for my new project say almost 7psi at redline with the current pulley size so i may have to machine a few different sizes to see what works best. I was told 6psi by Alpine tech support with no fuel mods, so that is where i am starting for now.
