    Rated 4 out of 5 by from fuel injection harness easy to install. works great on a stock 5.3 truck engine. the map sensor is to big to fit the truck manifold so it needs the hole enlarged or some type of adapter needs to be made. the fitech default is for 37 lb. injectors. did not see anything in instructions about changing that to the factory 29 lb. setting. after that change it worked much better. I plan to use another one on my son's next project which is putting a 5.3 in a early blazer.

    which style injector connectors are on the harness? And will I still need to hit the dyno to get the max out of it?

    Asked by: axld
    This will have the standard bosch style injector connections on it. We would recommend using a dyno to fine tune your engine.
