I have installed McGuahys (spelling is probably wrong), rear 2” drop springs on my 71k mile 2018 Tahoe premier with Magneride and the ride seems really rough now compared to before. Is there a calibration I need to do on the truck to get some ride quality back or maybe the rear shocks are just gone already?
The spring kit did come with a paper template to modify the rear shock position sensors rods, which I did shorten those sensor rods.

Thoughts?

Did you get the shock relocation brackets? Is the compressor running constantly? How much drop did you get out of it?

Yes, you can calibrate it. You need a bi-directional scan tool, not a Tech-2 (too old), Snap-On scanner or MDI adapter connected to laptop running GDS software for example.

I did install the shock relocation brackets. I think it dropped 2” and truck is even now compressor doesn’t seem to be running all the time.

Will this likely improve the bumpy ride?

big maybe, you dropped it so it's not going to the ride the same no matter what, that's 2" less of wiggle room and therefore changes the vehicle dynamics, you might end up with a small mpg improvement if the front was dropped as well, possible it could handle slightly better as a whole but that will come as a drop in static ride comfort
some of it depends on the functionality of the system as a whole, air pump, relief valve, shock performance, spring performance, wheel and tire size.
one way to look at it is imagine a triangle and you lop off a piece of one leg, the whole math changes, doesn't mean it is detrimental it's just different now.

I understand. But will calibrating help the ride even a little or no? Do you know?

Could just be a coincidence that you notice it now after the mod because you’re paying attention to it. When these fail they lock up. Try jumping on the running board on both sides, if you get easy up and down movement then the shock is likely fine. Remove the air line and look for oil in the discharged air, another sign of shock failure.

Measure fender height with airbags empty then reconnect and start the engine. If you get a big difference in these two measurements after the compressor is done pumping up the shock than you probably need to shorten those auto ride rods some more.
