Hey. Anyone running the rcx/celerator close loop fuel box. I got a PC5 without outo tune but dynoed. if anything happens to my box i,m screwed because the dyno place went under and none even close to me. It says plug n play from stock to 120 or more.

 

I can't find where it says from stock to 120 or more. I would say that if you are still running a motor with stock compression, just pipes and a/c changed it would work ok. Auto-tune systems don't seem to be able to adjust timing. I'm not saying it won't because I don't know how it works exactly, but they do have a disclaimer on one site saying not to use it with open exhaust like CFL's. It would probably depend on what your expecting it to do. I'm sure it can adjust afr's, but not to the degree needed for open exhaust.
