Anyone experience a significant drop in MPG after doing the stage 1?

 

My mileage remained the same after the stage one. It did surprise me given it's running richer.

 

You may want to state exactly what you did for your Stage 1.

 

My mileage has actually gone up. I don't know if you'd consider mine a full blown stage 1 though. All I have is the slip-ons and the dealer download. I get roughly 10-15 more miles per tank now than I did before.

 

Question, after your stage I did you go our and rev the **** out of it and drag race yourself thinking you felt all that new power? I would guess you'll have to keep track of the next few tanks of gas to really now whats up.
