i have stage 2 injectors on my truck, and dont have any problems, but i did install a bd diesel performance lift pump to push more fuel to feed the new injectors.

It's not the injection pump it's the lift pump and then the turbo. But I would not go over 100hp injectors on the stock turbo

Just like he previous post said, it's not the IP that is the hold up it's all the supporting parts. Turbo, Air intake, Exhaust, restrictive innercooler, Fuel Supply, etc... What it all amounts to is the more fuel the more heat to contend with so you have to find some way to cool the system down and keep it breathin fresh air.

I would go with a airdog or fass pump they work and have lifetime warranties plus the added filtration.

With 100 horse sticks if your still runnin the straight pipe in your signature the turbo will still get kinda warm in a hurry but as long as your keepin an eye on your pyro it will be do-able.

To get the full benefit of those sticks your also gonna need some kind of fueling box to fool the computer into sending the extra fuel through to the pump. My personal preference is the Edge products but that's purely a personal decision. Just based off feedback on the sites I would avoid Bullydog and Superchips though, they seem to create a lot a problems with these trucks.

My personal preference for a fuel pump is the MITUSA. It's completely mechanical so no electric motor to go bad and it runs off your flywheel so the more RPM's your turnin the more fuel it's pumpin when you need it the most as opposed to having your highest fuel pressure at idle and then going down as you push the pedal harder. Not that the FASS and AirDog won't both do everything you need them to, just another personal preference.

And definitely spend some time researching what brand of sticks you buy. There are good ones and bad ones on the market and sometimes the most commercial ones are not the best. Get some bad ones and you will be rebuilding an engine in a hurry.
