What are the cons and pro's if any of this?

 

I imagine the skunk2 im is better, but won't have iabs, but most people hate iabs it seems anyway.

 

don't know pros or cons

but I am running a skunk 2 im with a b16 ecu (p30) with no problems

 

I really don't see cons, it should give u a bit more pep, as for HP numbers, dunno. I do know the a skunk2 IM is better than the stock GSR one.

 

wouldnt the CEL come on without the 2ndaries??

 

Youll notice a difference mid to top end, its hard to explain but youll notice it. Itll be sluggish with the p72.
