Alright guys. Im still fairly new to tuning. I currently have a Cobb ap v3 on my 2012 gsr. I did notice a small power increase when i reflashed to stage 1v403 *beat my cousins charger after i did haha* Since then I have added a t1r catback exhaust and ETS test pipe.
I have bought a ets Fmic kit (3.5 in core) and ams full cold air intake and a grimmspeed 3port ebc. My question is can I add these 3 bolt ons (fmic, cai, and ebc) and use one of the cobb maps? if so should I use stage 2 or 3?? (yes i am aware that i need to use the intake calibration spreadsheet for the intake to custom tune a map) Any advice would be greatly appreciated.!

 

Hello!

I would recommend you also upgrade your downpipe and pick up our 3-port ECBS. We have not tested our Stage 3 mapping with the Grimmspeed version. Once you do that the Stage 3 mapping will work well for your car as long as you calibrate the map for your ETS intake. Here is a link to a video that explains how to make the changes to our Stae 3 map for your intake. https://cobbtuning.zendesk.com/hc/en...on-Spreadsheet
