Anyone had any issues with these on the dyno not making anywhere near the power they should, even bone stock?
Customer dropped off his car for some headers/pulley/cold air and we made a couple baseline pulls for him. Didn't log anything yet because we weren't tuning it until later but in 7th (1:1) it only made 480RWHP. It did make 536RWTQ which is right around where I would expect it to be. Haven't had a '17 on the dyno yet but all of the Z06's we have done were in the 545 range stock on our dyno which obviously makes much more sense.
Anyone got a thought?
