Looking into a decat and have read up that rex\'s run lean in this case.
I have a Hks induction kit and a Blitz nurspec backbox and a greddy profec b boost controller.
would i be able to run a decat with out it leaning out?
or would a midbox help to keep some of the back pressure to help stop this?
If you decat you\'ll need a new ecu like the apexi pfc. the stock ecu cant really handle any mods.
save and get a apexi before modding anymore the decat could lead to boost spikes
