Try a lift pump and feed all the potntial of the edge, should help a little or try LP or CNG as a suppliment fuel

checked your injectors lately? 13 is terrible for an lb7 even lifted id hope for 16 ish

Is that in town mileage or highwy?

it dont matter if its city or highway

Did you correct your speedo?

yea did that already

Your MPG check was at ? 60 or 80 MPH?
Just checking how heavy of a foot! lol

I get 17-20 mixed lv10 ppe. Something is wrong.

get rid of those 35's :)

I have 35's and still get the same mileage as stock and run a much larger tune. Something is still wrong.

Take your intake off and put stock back in and do the PPE air box mod you are prob getting too much air from what i have heard is unless your over 500hp intake will hurt the engine just my 02.
