Went for a little run in the mountains the other day and I noticed that the pipes INSIDE my RB catback where glowing red. I just installed power FC and right now its still tuned to the base map. i have no other mods besides the catback. anyone got any ideas? i searched and all i found was regarding MP and DP. nothing specific to the catback.

 

probably running rich. the base map is not the most ideal map for the FD. It's rich in most areas and awkardly lean in others. get it tuned and see if it still happens.

 

+1 ^^ lots of flames shootin down the pipes runnin really rich

 

fuel mixture is off, get it fixed pronto your EGT is off.

 

What is the condition of your cat if you have one?

 

i still have a cat. one.. im assuming its good.. 113k KM on the car.. stock exhaust minus catback. i actually noticed less backfires than with the stock ECU. working on getting it tuned but i wanted to wait for full exhaust and intake.. guess i can do it now.

it feels just the same as with the stock ecu..no power difference.. ill take it easy till its tuned..

 

I just installed a Pfc and have catback,intake and DP. Had it tuned and got more power after the tune. The tuner found spots that were very rich and very lean. My 13 year old clutch is bad so I'm getting a new clutch before we continue the tune. More power to come. If I were you I would get a downpipe before your tune.
