Hypertech power tunner for 20% better economy?
 

I'm trying to increase my MPG's. I read in Diesel Power that the Hyperteck will increase fuel milage by 20%. Anybody have this same experiece? How about being undetectable? 100% money back. Thanks

I doubt it WILL increase it to 20%. It might increase up to 20%, but I doubt it.

what do you want to do with it if you want it for tire size and code reading i would get one but if your looking for just increase in mpg

look into quad products like the quad race or standard or the xzt all of quads products increase fuel economy and they are the only products that i have seen increase mpg

i had the quad race and i jumped up 4 mpg and that was on the high setting for the race version
