Hey There everyone,

I had posted a few weeks back about getting a consistant 10.4 mpg with a toally stock truck using regular gas and a mix of highway and city driving.
It has been 10 days since installing a cat back flowmaster exhaust and under the same daily driving conditions I am seeing a 10.8 on my computer. Not too bad, and I also feel a nice performance difference as well as a great sound.
Next is the install of the Diablo programmer right now, and a test drive.

Kevin,

Thanks for the update.

Currently at 12.5 mpg on the computer through a mix of highway and city driving. At 3k miles - all stock. Keep those tires inflated. ;-) Off the dealership lot, mine were at 30 lbs per tire. Now running 40 lbs.

Kevin, I was @ 11.5 with appx 80% cty miles. Since my mods I am at 11.3.
I will admit that I need to check the tire pressure... It is low, I am sure. Probably 32 psi.
