i was wondering if anyone has any injector upgrades for their 5.9 - maybe the 95ish models. Whats sizeand brand? Do you tell any performance difference other than less MPG lol.

 

I am interested in this as well, but of course for my 5.2L. I've read where there are aftermarket injectors that have a better spray pattern and are much closer in tolerance to spec than the factory ones. I just don't want to spend the money or time on it if it is only a slight performance increase.

 

hey ron, what did you do to you throttle postioning sensor?

 

I drilled out the mounting holes on the sensor to allow it to be rotated slightly when loosely installed on the TB. I then used a digital volmeter to read the voltage on the sensor as I rotated the sensor to achieve the .75v reading. I then tightened the 2 mounting screws carefully so as to not disturb the position of the sensor, and took a final reading to verify the voltage was still at .75v. This seems to improve the transmission shifting to be a little better. There is a writeup on this on the forum that will give more details if you would like further information. Do a search for "TPS mod" or "TPS adjustment" and you should be able to find it.

 

thanks should have read up on it first but thanks! bump!
