Hey guys i just installed FP4r cams on my Evo 9 and its now running rilly rich, and misfiring a little at start up. i drove the car a little bit and seems to drive ok.
My AEM widband is stuck at 10.0

pre cams mods.
-FP green
-pte 1000 injectors
-Bolt on's
-tune

Any ideas would be great.

 

did u have it tuned already?

 

Thanks for the quick replay, no tune since, i couldn't imagine the cams making that "big" of a difference.

 

ya big difference tune is basically always needed when upgrading anything in evo

 

True that, everything changes with cam's.
