    P0633 code

    So I switched to hptuners not long ago, coming from a smarty can tunes truck runs way better, less smoke and more power happy with that. unfortunately I know have a p0633 code that refuses to go away even though its been disabled. for giggles I reflashed a smarty tune back in and the code disappears, set it back to stock and its still not coming up. as soon as I load a tune from hptuners it pops right back up. doesn't seem to matter what tune I load. I can clear the code with my snap on solus and it comes right back, some times it will come back but the solus doesn't detect it. thankfully truck stars and runs fine. anyone else have this problem?

    Thankfully it hasn?t cause any issues, other then trigged my ocd. But what I don?t get why is it still being tripped when the code was disabled ?
