that is a good deal on those injectors if they are in good shape. considering it comes with a resistor box thats a really good deal.
check my build thread and you can see my install of the resistor box which came out stock looking. as far as the injectors go, they are a direct bolt in aside from shaving the guide pin on them.
when you do install them make sure you get a new set of injector o-rings for the stock injectors and put them on the 390's. I tried to re-use the o-rings that came with mine and they leaked. just save yourself the trouble and by a new set from rockauto for $25 shipped.
the injectors run great on the stock ecu but not stock boost. I found the sweet spot is a minumum of 10psi and they work flawless. if you are runnin a rocketchip, you might not want to run them till Matt and I get a good tune set for the 390's. the standard rocket tune is too rich for the 390's so we are working together on getting a nice tune for his chip and the 390's.
the stock computer runs them just fine up to about 12psi which is where I stopped at till I get the wideband installed. I will crank the boost up and inform you guys what the safe limit of the stock ecm and 390's is.
