if so was it worth it compared to just a programmable tuner? if you would list nay other mods you have along with it. I am thinking about getting one and just wondering if it is worth the $400 it costs.

 

I was going to wait until they have them tuned to their exhaust they also raise your rev limit and I don't think a programmer does that.

 

i was thinkig about the pro com cdi box for my lil 400, seems to have more power at the higher rpms..

is the 400 carb'ed or EFI?

NEVERMIND I read your sig and it says "jet kit" so that answers that.

but we are talking about a EFI ECU, do EFI's have CDI boxes? I don't think they do but I could be wrong.

 

my manual says cdi box i cannot find ecu anywhere in my 04 400/500 manual
