Engine/Transmission (1998.5 - 2002) which for fuel mileage?

[CFast]

Do i get chip or injectors for better fuel mileage? thinking about an ez box, or inj, not sure which inj. Anyone?

 

[Bob Wagner]

no guarantee that either will increase mileage but the fun factor does come into play bigtime.

 

[CFast]

which should be done first then?

The ETCs (from a lot of previous posts) seem to respond to a box better than injectors as a either/or option. I have an ETH that I put a borrowed EZ on with no other performance mods and I noticed a VERY noticeable change in driveability (WAY faster response), but I didn't have the unit long enough to check mileage (probably down a bit with the initial improvement in POWER!). My overall mileage has improved with the Comp box I run now.

I noticed that after installing the timing box (Van Aaken) the mileage went up about 1 mpg on average.



Then went to DD1 injectors, and seemed to lose that mpg. Now Have DD3's and its about the same, maybe worse, but have been hot-rodding more than normal so its hard to tell.



The timing box seemed to be the best for mileage in my truck (ETC) w/ my driving style.

My mileage is really getting better since the mods honey!!!

It just shows a little lower because there's less rubber on the tires now.
