I have been running BR7EF for awhile now and I getting sick of the service charging system coming up so I am going to switch to some ZR1 plugs or NGK iridium's to see if that helps. I already have a Billettech alternator.. didnt help with that issue unfortunately.

Ive never got that message with the br7ef

I swapped plugs to everything under the sun to try and fix that issue. I guess the 2005 vettes are especially susceptible to this. It ended up being a crappy throttle body extension harness on my car which had a weak/sketch connection that finally fixed it. I tried iridium, zr1, and every other plug and wire though, bought billet tech, etc and none helped. Took me over a year to figure it out. Not impossible its' the plugs but unlikely imo
