Are these two together (optionB & endplate) good or enough cooling mods for a OTTP stage 1 or for custome tune with 2.8? i know the H/E is the way to go but since i already have option B AND endplate IM still debating on buying HE.

 

Those are both great mods to have and will only help you. The heat exchanger will help additonally as well but you can run the safely with just those without issue.

 

what will be my best route to go from GM stage 2 to OTTP Stage 1? what do you recommend with your hat off that is?

 

Most people get away with just running a front mount h/e, really depends how cool you want those temps.

 

Are you telling me Option B & endplate >= H/E?

 

dual pass>heat exchanger, although i recommend doing them both :p

 

Hey, it works for me

 

thank you guys. i'll stick with option b & endplate for now.
