Ok, being that all vehicles 1996 and newer get the OBD diagnostics port emissions test when im boosted and say im not running a cat, would my car be able to pass if i turned off the check engine light with HP tuners?? like being that the cars co levels and noX levels are down and passable.
01' Z24 5 speed

T4 Turbocharged
Built LD9
HP Tuners
If your not running a cat, you will fail. Easy as that.
Unless you have a hook up.
