I recently purchased a Cobb stage 1 for my Subaru wrx sti 2018. Which includes accessport and cobb sf intake. I installed the AP (no intake yet) to see how it was, and decided to put it in stage 0 (since my car is stock). Went out for a ride and it was giving me a rev limit of 3500-4000. Weird. So i decided to put it back stock and install the intake. After installing the intake I then proceeded to change ecu map to stage 1 + sf tune. 91. Went out for a ride and it was giving me the same issue of rev limit. I checked launched control and flat foot shifting and they were both set to 8000 rpm, so that wasnt the issue. I decided to run it with that tune but without flooring it or going "hard" and then i get a check engine, running rich ( as expected) cobbsupport take weeks to answer an email so i decided to give this forum a shot. AP is up to date, i redownloaded the tune in the AP jic that was the issue..I pretty much did so much and nothing else comes to mind. Any one else had this issue?
