After installing the Banks (which I love & highly recommend)cat-back & an Airaid intake my MPG has gone on average from 14MPG to 16.5MPG in city. Not to bad for just an intake & exhaust. I might add a tuner & headers(which don't look to fun to install) after this years tax return.

 

I get about 16.5 or so all-local driving. I have a magnaflow muffler, not a full cat back. Thinking about a tuner when the 9100 comes out for the 04’s.

 

whats the differance between the 9100 and the 1714? just curious.

 

The 9100 aren’t out yet but the difference is that it’s a custom tuner for “truck specific” as the 1714 are for all 2004 models. I never had one but there’s supposed to be a big difference in HP & torque gains between the two. Check out Troyer’s page, it describes both models and what you can expect.
