Trying to figure out what supporting mods I need to run an Invidia catless downpipe and Cobb SF intake.
What I have:
-Catback exhaust
-catless downpipe
-intake
-turbo inlet
-ID1050x injectors
-aem fuel pump
-Cobb fuel pressure regulator
-accessport
-grimmspeed boost controller
-aem windeband

I know im going to need a protune but is there anything else I need? everything else is stock.

A external wastegate upipe will help you greatly. Sometimes catless dps will make the vf48 over boost. Mine overboosted to 24psi 馃槄. It will give you greater control of boost, and they sound badass.
