I just received my procharger kit! Next step is a Cosworth plenum and fuel rails. I am looking for some insight as to what size fuel injectors I should use for a 7-9 psi setup? Also, if anyone can give a heads up on idler pulleys and if I should stick with the procharger ones or what? Finally, I am always wanting to get the most bang for my buck, so with that being said would a full stand alone ECU (Haltech) work better than a reflash such as Osirus? Overkill with the Haltech?
