The plague of MRC!
I have been working on getting my "full post" together regarding the work I've done to my 2015 Tahoe LTZ (with Magneride and Max Towing package). New Nitto tires just went on last week.
I worked with a company called
X-ineering, based in FL, to help "delete" my MRC. Max there develops track cars, Corvettes in particular, but he created the GM Shock Sim for the magneride system.

I have about 2,750 miles so far with the GM Shock System in place. Basically, Max has developed electronic circuits that "tell" the on-board computer that the MRC is working and functioning properly. When, in fact,
you have disabled the MRC system completely!!!
I am running the Fox 2.0 Front Coil-over full assembly (set at +1-5/8" ride height; arrives set at +2")

AND
Bilstein B8 5100 series rear shocks (shocks for 0-1" lift; I have the rear on a 1" coil spacer).

Since I do get off the beaten path once in a while and the idea of this entire Tahoe project was to make the truck more capable off-road, I purchased new rear coil springs (z71 version) and installed those when the rear shocks and spacer went on. Did you know there are 5 different rear coil springs for the Tahoe? The pair cost me $95 on eBay.
THE RIDE IS AMAZING! The rear end of my Tahoe used to slam hard and just the smallest of bumps and holes in the road and the beast would ride like I was driving through craters.
Now I am able to be aggressive with bumps and not worry about passengers complaining in the rear. You can feel the improved balance and control with the Fox shocks up front and they just eat up bumps like nothing I had before. FYI - running 275/60r20's now. Gained just over 1" on overall tire diameter and a sidewall increase of just over 1/2". Between the new tire size and the adjustable leveling Fox coil-over assemblies, the front fender now measures 3.5" higher than original and with the 1" spacer in the rear has a very level stance with just a slight rake forward still. -Picture is after the suspension but before my new tires...I SAY GO FOR THE MAGNERIDE DELETE! Well worth it in the long-run I think compared to replacing the MRC. ALSO - my front MRC struts were leaking at 36k miles when I purchased the 2015 LTZ certified Pre-Owned. They replaced the front struts after I called them on the leak. That story is a whole other animal though...SAFE RIDING!
