    Default 98 Silverado 5.7 vortec

    I want to remove the egr and the rear 02's but I cant seem to find the info on what all needs to be turned off. Been awhile since I used efilive.

    I should be able to figure out what dtc's to turn off when they throw a code I guess. Has anyone removed the evap system on one of these?

    These types of questions don't get much response do to the legality of them. Open up a tune for a vehicle that does not have an EGR and see what the differences are in the diagnostics tab as compared to your vehic. You can learn a lot from that.

    there's so much not documented in the def for this engine it's about impossible to do things.

    Only thing I see possible for EGR is EGR enable MPH, raise it.

    There is a switch in other software to turn off third O2 and one that is really useful to run Open Loop, as well as many more. Really wish EFI Live would spend some time on this engine.
