Uncoated TTI for break in period?

Hey Dartdale - Are you running a flat tappet cam or roller cam? Roller cams don't require break-in.
Talked directly with tti rep at several shows this year before I ordered mine and was told the big problem during any break-in is possible lean carb conditions causing high exhaust temp. Sustained 2500RPM running during break-in with lean fuel could cause excessively high exhaust temps that will permanently discolor the polished ceramic finish.
Roller cam and/or rich fuel carb condition will help avoid this.
Good luck with whatever your decision is.
