Tuner Rattle
How Much is too much? or is there such a thing. I'm talking about the extra diesel rattle I get on a cold engine when running my Bully Dog. I expect theres got to be some because of the fueling going on. It does quiet down as engine temp comes up. I know from reading here that some tuners wont alow more fueling until temps are up. Curious if it will hurt anything. Thanks.
