I am running the 87 octane program , i removed the afm and adjust my tire size. I currently average 17.1 to 17.3 mpg on a tank. Where as stock I was getting low 15's for mpg. I don't do any highway. I am on duratracs 275/65/20.

I ran the firm shift for a week. It was great then a few times I noticed the transmission had a delayed shift so I removed it. Now I noticed it still does it with the stock program. I may try the throttle boost.

  No, because GM still doesn't sell the programming update that allows it to work for trucks that didn't come with it from the factory.

  If you would read instead of trying to flex your big bad fox body. I wasn't talking about larger injectors was talking about going from a single shot nozzle to multi hole nozzle. Which it's common knowledge that they provides better idle quality and better throttle response due to the better atomization. But hey if were whipping dicks out I noticed a huge difference in thottle response when I switched out my factory single hole injectors on my 88 fox body

  While it may be true that multi hole injectors atomize the fuel better, it ain't going to make a difference on your stock truck. I have USCAR EV6 50lb/hr injectors in my turbo 6.0 foxbody with stock cam/valvetrain, I didn't notice a smoother idle or overall driving with just the larger injectors. Even if they put out 26lb/hr at 4 bar pressure like you need, all of the other data won't be the same as the GM data. The offset vs volts, short pulse adder, min pulse width and flow rate data all need to match the injectors installed, no way all of that stuff would be the same.
