 I too used Witchhunter. I was very satisfied with the results, turnaround
time, etc.

Yes, I used Witchhunter (google 'em) to clean and flow test / rebuild my RS2
injectors. The testing report will show you the difference. Mine was subtle,
but eliminated a potential emissions issue. If you know the history of
running a good clean fuel and you run a good cleaner, Lucas comes to mind,
then I'd just replace all the seals and leave it be (assuming there is no
known problem). In my case, It costs about $100 US for the peace of mind and
knowledge on the actual cylinder to cylinder slight variations, but YMMV and
a good cleaning may have dramatic results. BTW, a new FPR was my ultimate
culprit on my emissions issue.
