Are all you guys serious? 19.2 MPG!!!??? I'm green with ENVY. My darn truck just loves taking money from my wallet. I get 14.8 MPG and it STAYS there! I removed the
running boards and it gets 14.7 MPG, but with the factory
running boards installed, it gets 14.8 MPG. Weird, must be due to aerodynamics factor or something. I will try the HC mod one day. And go with the unplugged ECM for 10 minutes as many of you doctors recommend it.
Thanks.
