IP does not have to be touched. However checking the IP timing, using the RIV light is probably a good idea. Not because you replaced the injectors, just because it should be checked.

I wouldn't have anyone who thinks the IP has to be tuned work on that car. No offense to them but they just don't seem to know much about 603's.


Ask him this:

How do you time the IP on a 603, and what is the IP timing supposed to be set at?

If the words RIV light and 15+/-1 degrees don't come up, find another shop.
