I know Cobb recommends a full TBE for stage 2, but I've read that it's still okay to run stage 2 as long as you've switched the OEM cat out to either a test pipe or HFC. I am still waiting for my HFC to come in and will upload the logs once I do some runs. I just wanted some opinion from seasoned Evo X owners. Am I safe to run Stage 2 with just the ETS Intake and ETS High Flow Cat? The map will be calibrated for the intake of course.

 

Yea i ran the cobb intake and ETS highflow on stage 2 and it was all good.

 

Thanks for responding! Do you know how much power you made? Any 0-60 or 1/4 mile runs?

 

no sorry i never did the virtual dyno thing
