I have a 01 with bahf,quadzilla,air dog 150,triple disc torque. would like to do bigger injectors and cross tubes possibly. How big can I go with out problems? do I need bigger injection line? had a dragon fire injection pump on something went wrong after 2 months have metal chips in lines and where they meet cross tubes. getting new lines cross tubes seem okay.

BEFORE the turbo... After the turbo is 300-500*F cooler... Also you want to be on the 4,5,6 bank which is hotter than 1,2,3 bank. #6 piston is the hottest. It all about making sure you don't burn up a piston so you want to measure the close to the engine. After the myth of pyrometer wiping out a turbo I've never seen one reported yet here, or a host of other forum I've been around...

Thats what I've been told, just wondering why bigger engines have them after the turbo. Maybe I can find a 5 gauge pod and run one before and one after since my exhaust system has a port for it after the turbo already.
