I just got a 99 Dakota 3.9L. I am looking for any mileage programmers that work. I do have a 300HP srt4 for fun, so I am not looking for any go fast bits, It does have CAI and throttle spacer.

 

superchips is best, and i hope you didnt buy that TBS.

 

i heard that for the 4.7 it actually works but then again idk. anybody know if it works for the 4.7?

 

it all came on the truck

 

yeah superchips, i noticed a slight increase in power and economy in my v6. i have cai, magnaflow exhaust. i usually hover around 20-21 mpg

 

a tb spacer WILL NOT help any vehicle that is multi-port injection, on a carbeurated engine, and possibly on a throttle body injection engine, all it can do is give a little more space for the air/fuel mixture to "mix" before it gets combusted.

 

see thats the thing, is like there are some people that say that they work (TB's that is) but other people say they don't. does anyone have one that works for them? idk like it might be a good idea cuz they are pretty cheap huh? just let me know

 

i rather see $40 go towards a tank of gas or $$ towards something for my truck. and that something will not be a throttle body spacer.
