I am looking for some insight into how much tempature will affect a good tune. Been running a 500" BBC with 14:1 comp on a 275 tune with a big shot. 7 degrees out and 6lbs flowing on C16 with 3932 plugs. Tune up looks good and has worked well up to now. With the colder weather setting in What should I be doing to safe gaurd the motor? Been racing in 75-85 degrees and now its into the low 60's at night.
