So I was looking into getting my stock injectors worked on by RC Engineering as part of my initial tuning up my 1988 RX7. I figure this would help a lot as well as being a preventive measure against possible fuel leaks. Thoughts?

 

I've heard that both Witch Hunter and RC Engineering are reputable companies. I had Witch Hunter do 2-3 sets for me and was satisifed with their service. If your car has a lot of miles on it, it would not hurt to have them cleaned. They will also flow test them for you so you know how close the actual volume is between the two units. As you note, they also install new o-rings so you know you won't have leaks....unless you mess up on the install.
