C7 AFM valve delete/removal after tune???
I know this topic has been previously discussed, but my question is:
Once a tune has been done to eliminate the 1-4 skip shift and also eliminated the AFM valves from closing, can fuse #32 be pulled without throwing the CEL and/or can the AFM actuators be removed as well?
I have a 2015 Z51 M7 with the following mods:
Bullet exhaust with NPP deleted, fuse #42 pulled and actuators removed.
Borla catless x-pipe
ARH catted mid length headers
Halltech carbon cai
The car was tuned and the AFM valve function was deleted, so now they stay open and the 1-4 skip shift was also deleted.
Thanks.

What's the purpose for pulling #32 
Would those mods/tune void your 5yr powertrain warranty?

You removed the valves, there's no reason to pull the fuse. Fuse 42 either for that matter.
