If you want dependability I would stick with stock injectors, HPOP seldom go's bad so I would leave it alone also. For a fuel return, I have had good luck with the FRx from Riffraff. With all the mods you have you should be able to get a extra 100 hp out of stock injectors. Truck sounds like a tow monster the way you set it up.
Thanks for the reply. I am not happy with the FRx as it requires me to time out my fuel pump before starting. If I start it before waiting the engine cackles badly.
