I have a downpipe CAI MBRP exhaust and a tune I use 91 but would I have to get a flash tune or dyno tune to use 93 or will my car work with 93 with what it has?
What mods make the hyundai a little more reliable and run better? i run cheap gas and looking for spark plugs heat range 9 because i’m FBO no tune
