Get efi live from a reputable tuner the h&s is shit tuning and there isnt support for it any longer. Exhaust and unplug the 3 connections under the hood and you're good to go. I've done many a lml this way and never had an issue. I have yet to see or even hear of an lml blowing the egr open under high boost. They arent like the older years. I ran mine with no blocker plates on a hotter tune than most would dream of asking for, for years and thousands of miles and never had any issues.
