I have a turbochaged F23a1 running a low 8 psi, and will be running around 14 once the pistons and rods get here. For ignition right now all I have is the MSD BTM to retard my timing if needed but it isn't the BTM that boosts the ignition. My question is, is it worth getting MSD SCI or 6AL ignition, will it make the car peppier. My other concern is are the MSD ignitions amplifiers, my additional injector controller uses the rmp signal from the distributor and says it can only handle 12V and so I know I can use the RPM signal like I was hooking up a tachometer but is that nessecary! I also have new 2 stages colder spark plugs and new OEM wires.
