Emission compliance is very important to Hamburger’s Superchargers, so our engineering team has worked hard to ensure that our supercharger kits meet the compliance standards set by C.A.R.B. (California Air Resources Board) for those vehicles we offer a supercharger kit and PCM calibration for. Our supercharger kits are certified by C.A.R.B. to be 50- State Emission Legal, and are covered by the appropriate E.O. numbers. The supplied calibrations are intended for stock vehicles with or without a cat-back exhaust system, but with no other engine modifications made.
