I put the Stage 3 PCM on and went back to stock plugs as I was sputtering at high RPM in second, runs and pulls really hard. My question is, what do you think the best cooling mod would be, Meth, H/E, or Dual pass? I wanted to try to use Meth to run the 100 Octane mode, so I was partial to that route as I'd get more HP and cooling at the same time. What do you think?

 

stage 3 what? GM? it should've came with dual pass...

 

Sorry, Yep GM its in my sig, no kit, got the PCM only.

 

yeah i beleave stage 3 gm comes with a dual pass( and if ur a gm) you have to get ur comp. unlocked before you can add meth ( atleast for the tuning side of things). but if u can i would definatly do meth and a cheap heat exchanger just to be on the safe side.

 

the more cooling mods the better. id go with a 2nd heat exchanger and dual pass. people have run meth using the 100 octane mode, aparently it does work alright.

 

get dual pass. extra h.e atleast a cobra one. and meth. and if u can the stumod

 

get a fmhe and or meth for now, meth before the fmhe imo, i'd wait till the single pass comes readily available because single > dual, i'll prob be switching mine over when someone comes up with a marketable one, looking to watch zzp's very closely.
