I bought a used 99 about a year ago and never really thought about the tsb for the power increase until a friend brought it up over the weekend. Was there a mark or or something done by Ford for me to check?
Thanks

99 Fix was for the intake, restrictive mufflers and new PCM tune.
Unless you are running stock mufflers and tune then those should be fixed?
I wonder if the green or blue mark would still be obvious after 14 years?
Why is the green better?
Lol, ok but why would the acid dip be better then extrude hone.
extrude hone leaves the surface rougher when "done."
extrude honing results in a very smooth surface while acid dipping leaves the a "sock like" finish.
