Question about stage 2 tune
Hey guys I have a 2013 Subaru BRZ and I have a JDL UEL Catted header, planning on getting an MXP Comp RS Catback exhaust soon as well. I watched an FT-86Speed video and noticed they directed that stage 2 is for catted headers. Any tips or advice before I use an open flash tablet for stage 2?
