I bought some injectors from you a while back. I was wondering if they are flow tested or anything. I was thinking of having them tested to eliminate them as a problem to me blowing my second head gasket. They only have about a thousand miles on them, so I don't want to do it if they are all ready tested at the factory.
We only flow match the new FID injectors, though the ones in this listing are still going to be within 2% or less. There will be a much greater airflow difference cylinder to cylinder on your engine than there will be fuel flow. Blowing HG's is 70% of the time the tune, 15% of the time a warped deck/head, 10% of the time improper head bolt torque, and probably less than 5% of the time a fuel flow imbalance caused by injectors.
I'm more concerned about the possibility of one of the injectors being a little blocked up with some dirt or something. Everything was brand new when they were installed, including the fuel filter. What do you think the chances are of that? Or would it be real obvious if one was blocked up or blocking up?
