Larger Injectors Vs MPG

The question I have for some of you is, did your MPG go Up or Down after installing larger injectors in your truck? MPG, up or down by how much and how big are the injectors you got in? I'm looking to put some in soon, but didn't want to kill my mpg by going to big. Thinking of 185cc or 205cc. Thanks for any input you can give!

Honestly 205 is too much for daily driving if your asking for MPG, max is 190's. You can still get decent mileage with 190's with the correct tuning.

That is a hard question to answer for me because there are times it does better than others but overall, I would prolly say went down over stock, but even though, I say...
"It's just a Granny Truck" , it usually don't get driven as a granny truck. I average about 16 mpg everywhere I go but it does go up a little on the highway but not much. The best we have ever gotten was with the Predator, 22-24 mpg, but that was pre-injectors. I have 175's Casserly injectors.

I didn't poll because I'm in-between.

The mileage didn't go up or down. The larger sticks require me to drive differently. So, mileage stayed around the same. What I lost was the fun to drive factor of having bigger sticks. With larger stocks, I have a larger turbo, so very little hard accelerations. Smaller sticks, smaller turbo, more aggressive accelerations. I have been up and down in regards to performance for quite some time. I’m at a steady 15.5 to 16.5 mpg (400hp to almost 600hp).

I have had a number of different sizes and anything over 155's the above comment is true. 155's yeilded a measureable 1.5 to 2 mpg on the freeway consistantly.

by what i understood the stock fuel system cant hardly feed the stock sticks alone under WOT so bigger sticks are kinda pointless without an upgraded fuel system and supporting mods..correct me if im wrong..

You are very correct. You WILL have to have some sort of support fuel mods. I had only a Regulated Return with my original 155's and the stock could not keep up, so when I went to the 175's I added the Reg. Return and it still was not enough at WOT. I then added the FASS 150/180. ( the LOUD one) LOL and I have good fuel pressure at WOT throttle now. Yes you will need sometype of fuel system for bigger sticks, and IMHO, if you are told diffrently, I will big time disagree with them. But then again, I am just an old lady! LOL
