I have a tad more than 7# at WOT. Most of the time I don't get lower than 12 deg timing, but it all depends on the weather and if my truck is already hot.

I can help w/ the new injectors if you know their exact flow rate.

-Couple of hints: When you go to install them, let the truck sit overnight first. That way the fuel lines arent pressurized. When you install the injector, check the size of the O rings. I reused the blue top O ring because it looked thicker than the ones that came w/ my new injectors (buy some new ones if you have time). Also, lube the injector O rings w/ oil, it helps them slip in easily and create a proper seal (I used plain 10w30).
