I have a friend who has a 02 6 spd with a tst box and is wanting an upgrade in power and mileage. which injectors are the best made to provide better mileage?

 

I let my buddy put my JR stage 5 injectors in his truck one day and it made his mileage go up from 19 to 26! My truck the increace was only like 2 mpg. Every truck is different.

 

I've been real happy w/ my jammers.

Is that mileage calculated by hand or is it using the overhead?
The overhead will read high when you use larger injectors.
Mine reads 24-25 and it figures out to 17-20 with a pen.
I'd say to use the mach 1.6 injectors and a Smarty for best mileage.

 

hahahaha Is that overhead console lying to you again?? 19 is good

 

would just tips be better for what hes wanting?

 

Tips are a lot cheaper! I believe that the smaller Mach injectors do achieve good atomization which equates to better mileage, but at 600 + for the cheapest set, you could buy jammer nozzles and use your cost savings to buy way more fuel than any injector could save you in 5 years! Unless you put on 750K miles per year, then you might break even. Although new injectors usually get better mileage, it is so hard not to hot rod once in a while cause you have so much new found power that you will not get better mileage overall if averaged monthly instead of averaged on time on a road trip where you never gave it over half throttle and ran the cruise forever.
IMO "in my opinion" injectors, chips, NO2, water/meth, and bigger turbos should never be purchased for better mileage, they are power upgrades and will never net more economy! Human nature will never allow them to pay for themselves. I love power, and my upgrades give me that along with some cool gadgets to look at while i'm driving.
