2.2" pulley folks w/ 7th injector?

Just want to figure out if the 7th injector can run the 2.2" pulley without further fuel modification, ie. 190 LPH Walbro upgrade.

Just thought I'd ask if anyone has tried it. I know of one member that has the 7th injector with 190LPH fuel pump, and even with the 2.2" pulley, was running too rich. Perhaps an AIC timing control unit might be sufficient for folks with the 7th injector to run the smaller pulley.

As-is, the 7th injector does only a so-so job of fixing the lean-out problems... To run the 2.2" pulley you might consider the URD 7th injector upgrade kit as well.
