I've noticed that my ZR1 RM horsepowers are different. I have my older one that has been driven a lot, and I made a new one, (two new ones actually trying to figure this out) and the new ones, even with every mod (I quadruple checked) have less horsepower than the old one. It's only 2 horsepower less, but the reason why is bugging me.
It's not the oil change because the new ones have never been driven, and the old one has been driven a lot and I've never changed the oil. I also triple checked to make sure I wasn't comparing a Z06 and a ZR1. I also checked the tunings to make sure it wasn't due to weight load or performance % downgrade or something. There isn't any difference in the tunings (that I know of) that would cause that.
All ZR1's, all have every mod, and the new ones have two less HP. Any ideas? It's trivial I know, but I'd like to know what is causing it.
