OK guys. Take a look at my sig. Taking the present mods into consideration, what could I expect a set of 50hp nozzles to do to my fuel economy, both unloaded and towing around 10,000 lbs? I'm after a MPG gain more than I am power. I know I may be able to gain MPG's with an injectable like propane or water/meth, but I really don't want to mess with an injectable. The less tanks I have to fill, the happier I will be. I've been told I could expect a 1-3 mpg gain with the nozzles, but those figures seem to be based on a stock truck. Anyone here with similar mods that have seen an increase in fuel economy by going to bigger nozzles?

Thanks guys.

 

Are you wanting to run just 50hp nozzles? There is a flux nozzle that gives you 20hp it's sized smaller than the stock OEM. This decrease in size still adds 20 HP through tighter, less leaky tolerances, lighter internal pintles that waste less energy... If you're wanting MPG I would look into those. A 50hp nozzle will also increase economy but not as much as the above nozzle.
