I was always on the fence about "break in" also. When i picked up my SS i decided to do the break in period. A couple guys i know did not and really got into them right away.
Nothing scientific here and certainly NOT gospel but, here are some results i will share.
Last trip out to the drag strip all 3 of us made 5+ passes.
ME A6 100% stock other than a CAI.
Other A6 (Tuned - catback - CAI - catch can )
M6. (Tuned - catback - CAI - catch can)
My only losses of the day was by .1
Now i realize you can call the M6 a wash due to many factors. But, the other A6 "should" have beaten me handily but it didn't.
I matched both these cars within one tenth.
Possibly due to recommended break in period i performed?? Maybe it is.
