magnum converstion thoughts ??

I haven't done the swap but I have some experience tuning some fairly agressive EFI magnum systems and am planning to run an EFId 408 in my dart.

One thing worth mentioning is that if you are going to use forced induction or a cam that is going to pull less that 15" vacuum at idle, I would ditch the crappy JTEC system and go with a standalone. Radical setups with JTEC computers run like crap. JTEC PCMs are very rigid when it comes to MAP signal and are pretty much stuck on an AFR of 14.7 in closed loop. I have had great luck with Accel Thruster DFI, but I will probably run megasquirt on the dart for cost reasons. Also with an aftermarket standalone PCM, you can just use a dual sync distributor and forget all that trigger wheel/ CPS complication.
