I was watching all Bobs awesome videos this morning and after I did I clicked on how to improve MPG in 07 Silverado link. I landed up reading for almost 3 hours about this stuff. Anybody ever tried it. Sounds kind of 2 good 2 be true. You can build you own kit for about $75 and up . Then you have 2 buy a chip thing to mess with the PCM/ECM. Or you can buy and kit ready to install from $700 and up...kind of like alky I guess.
I was thinking about plaing with this on my 05 Serria with a 5.3 gets about 18mpg would be nice to bump it a bit.
