To be honest I did not know what psi the stock injectors were, I told him there is one bad injector and recommended replacing all of them. I installed what he gave me, I took the fact he is such a corvette historian that he knew what he was getting for me to install.

He call me now and then to tell how much more power his car has with the new injectors. so I an not sure it they made a difference, at least he is driving it instead of sitting around.

Have to agree with everyone else....I got a full set of injectors from FIC .can't remember what I paid but sure it was under 250.00 and that's shipped to Canada too. Did it myself for the first time in under 2 hours on my 93. Spilt gas everywhere but lesson learned. Go to FIC do it yourself you won't regret it.
