When I return to the states I plan on modding my 11 gsr a bit more to include map ef2 and GSC s1 cams. Current mods are full tbe, short ram intake with cobb inlet hose, Cobb stg2 tune. I now I'll need a new tune, but I'm not sure as to what if any other supporting mods I'll need! Any insight is greatly appreciated. Thanks in advance guys!

 

I can always help you when you are ready. I would suggest doing a downpipe or even one of our o2 eliminator downpipes as long as you are replacing the turbo, a good catback, and some fuel supporting mods to really take advantage of that turbo and a tune. More definitive suggestions would really depend on your goals, choice of fuel, ETC

I currently have a down pipe, hfc, and catback. I'm just kind of lost when it comes to fuel parts, like what size injectors, new pump, those kinds of things.

 

Deployed?
