back the low mpg i wonder if the stock cats could be a cause? even though on my truck the exhaust feels good out of the tail pipe and all but i have herd other that removed or clean the cats out and got a huge jump in mpg saving.. but i wonder what it does with all of these O2 sensors this thing has ya know and how they will effect the truck. but dang i need more then just 10mog city/highway i need like close 20mpg would be great
I agree with needing more MPG's I could use a few myself. One guy mentioned that I bought a tank so the MPG's should be low....LOL He was right but I wished he wasn't....

I've heard / read it it both ways. Some say it made a difference and others said they felt like truck ran better but didn't see a difference in MPG

a autozone worker has a 02 i think and he said he went from 12 mpg to 24mpg by reworking <lol nice wording.. just by ding that alone. now that i would do in a heart beat ya know.

true on the tank part. but still why were they advertised in having this so call great mpg when in real life they dont? right now my truck gets 2 mpg better then my 69 Olds does which isnt all that great really. if it wasnt for the snow/salt on the ground i would drive my olds cause it is much cooler and still turns head and sets off car alarms yet lol
Nothing wrong with turning heads and draining batteries via car alarms. LOL

One of the best ways to test your cats is with a temperature gun ( TIF Instruments Infrared Thermometer Pro 10:1: Heating, Cooling, & Air Quality : Walmart.com ), the other is a back-pressure test.
The outlet of the cat with the engine warm at 2500 rpm should be hotter than the inlet - if the inlet is hotter then the cat has a restriction inside and should be replaced.
For some reason I only average 14.5 mpg out of my 6.0L. I can average 16.5 on the HWY but choose not to. Driving habits have a huge affect on not-so fuel efficient vehicles.
One more suggestion is the old "put an egg between your foot and the accelerator pedal."
