I have a 2021 lm2 with 150,000 miles. I had to replace the number 3 injector around 140,000 but that’s all I’ve had to do.

My 5.7 has a big over 210k miles, 338k km, and the only engine specific work, that wasn't routine like plugs and wires, was the main fuel injector, some kind of gasket on the intake or something not the head gasket, and that's it
Holy ****, they fit. FOUND IT. The injector that has been so elusive that flows more than stock (exact % will not be disclosed at this time as I do not want to upset any advertisers with my findings....) is from the GM 2.0 Ecotec motor: - GM LNF 2.0 ECOTEC OEM Injector Part # / Bosch Part # : 12636111 / 0 261 500 112.
