No, I haven't been sniffing the exhaust again. My boss just supercharged his SRT-10 and picked up quite a few mpg. It looks like 6+ mpg on highway! What have you guys been seeing with your setups. My wife might loosen the purse strings if I can pick up some fuel economy.

 

Uh...It's worth a try but I doubt the "let's get a supercharger 'cause we'll get more mpg" is going to work.

 

I went from 13/14 with my N/A 5.3 to 19-21 on the freeway with the turbo. That is, if I keep my foot out of it

 

If you have alot of self control you will pick up some MPG with the Radix install.

 

How much we talkin here?

 

Honestly IMO relating truck and MPG is like relating civic and towing in the same sentence...

 

I did pick up about 2-3 mpg with the suburban after the blower, but honestly I think it has more to do with the fact it went from factory stock tune to a more efficient SD setup that uses the MAF in cruise. went from about 13ish driving like an old man on the highway to 15 on the highway.

that being said with my mix of mostly city some highway with a heavy foot its always in single digits.

 

+1

 

I still only get around 14 mixed driving

 

Thanks for the input. Most of what I've read or heard is you may pick up 1-3. Self control is an important factor in this. Most of my mileage is highway, so I was hopeful I could see more. Looks like purse strings are still tight.
