Took my truck for visual smog check and the technician told me that computer will fail any tune (even on stock) on ECM without C.A.R.B. EO sticker. I told the technician that nothing was deleted on my truck except tunes. He said it doesn't matter if all emissions intact, the computer will check if any tune installed will automatic fail. The technician said go with legal tuners with EO Sticker. Sigh... I know EFI Live is awesome but couldn't find any tuner who have C.A.R.B. approved for EFI Live. I am looking at Edge Evolution CTS2 but doesn't like pulling fuse every time changing tune. I checked Banks Power and it does have on the fly tune. Any other turners I should check before giving up EFI Live tune.
