I have a 2013 evo x and I cannot brake boost. Whenever i hold the brake and start to build boost my car will have "dead pedal" where the gas pedal no longer works for 3 seconds. Has anyone figured out howto fix this? I know guys with 2008s that can brake boost so this was implemented sometime after.

 

This is not street racing related. I do not promote that. This is for personal reasons.

 

unless someone defines those tables in order to disable throttle cut on brake, you would probably have to bench flash to a 2008 or 2010 rom if you really want that feature.

 

tune can fix that im sure

 

2011's starting with ROM 56890009 started closing the throttle plate hence disabling the ability to brake boost.

As momostallion said you will have to bench flash to the 2010 55570005/6 ROM to have this feature.

 

^^^ Figured that out trying myself. Honestly isn't worth the hassle.
