Hello. I have a 2011 GSR. I just purchased an ETS quiet exhaust, COBB high flow cat and a COBB short air intake. What map should i use for the mods I am about to install? I use 93 octane fuel. Thank you and I hope this is the right place to post this.

 

I would use the stage 2 map with the intake update. You can modify the stage 2 map to work with the cobb intake. There's a video showing you how to update the map on cobbs site.

 

I would run stage 1 93 map until you get a downpipe. You can find the guide to scaling your intake with ATR here.

Ok... I was ready to run stage 3. I didn't think a downpipe mattered all that much on evo X

 

highly recommend the ets downpipe. aaaand stage 2 with that.

 

Without a downpipe there can be excessive heat build up that can cause detonation, we do not recommend running a stage 2 map until you have a full turbo back. A stage 3 tune will need a 3 port boost control solenoid, it is not compatible with stock boost control solenoids.

Are we talking about just the piece below or from the o2 back? I was under the impression that just the piece below doesn't yield any gains but would like to know Cobbs take on it.

Yes or any of the other downpipes on the market will increase flow and aid in heat transfer.

 

Ok. I installed my cobb high flow cat, ets cat back and cobb sf inrake. I used different maps, including a stage 3. Car seems slower in all maps I tried, and it is ridiculously loud, to the point that I hate driving it now. After loading different maps, with each one I tried, I get a service engine soon light.
It comes on after driving around for a few miles, usually more than 10 I think.
Right now I am using a stage 1 map, ver. 403 that I changed the values in for the new air filter, using access tuner. I did follow the directions on cobbs site. The car runs a little better, still very loud, but pulls harder when I step on if. Unfortunately I still got the engine light on, code p0420. Max boost was about 25 psi, only one time. Normally doesn't go over 22 psi. I had 2 counts of knock the most. Temp outside is 46 degrees.

 

Usually when you change your exhaust it gets louder, if you don't want loud you need to stick with the stock exhaust. Which ETS exhaust did you install?
