1997 PSD injectors and Quadzilla 4 bank chip

I keep reading about 97 stock injectors and how they can only handle a maximum of 75 additional horsepower from a performance chip. Is this true or can the stock injectors handle more? If they can only handle 75 horse I do not want go all out on a chip. Does anyone know about the Quadzilla 4 bank chip with commander control system? Thanks for the help.

I think thats about right. Seeing that the 97 injectors are 120cc and the 95's are somewhere in the 90cc's, people say that the 95 can only gain about 40hp.

Typical cummins owner.

I don't know anything about the commander, but you are right about the 75 ish hp gain. You will max out at about 200 hp to the wheels, maybe a little more. This is true with all OBS trucks, except for a '97 California Emissions trucks, that came with 120 cc split shots. Most '97's had the small injectors.

Stage 1 injectors will get you to around 300 hp with a good chip and intake/exhaust.
