I see a few problems here one is do any of you have a 25,000 dollar flow bench to be able to match all 8 injectors to identicle flow rate because if you dont then there is no possible way to make your truck run right. and 2 is there is physically no way to get more than 138ccs through a stock nozzle. to reach the 140cc, 150cc, 160cc you have to change the nozzle. lastly any injectors over approx. 165cc you have to go to a hybrid design other wise when you create that kind of injector flow at an idle you will dump so much fuel in it will actually "flood the cylinders" with raw fuel and the engine will not run.
