Hey ppl, So a hand full of years ago i did a 91oct tune on my 2010. Deleted the EGR and rear O2. WELL i ran the car in flooded waters, Opps . Well the car sat for 3 years before fixing it up. Been driving it every day for 3 years. I dont know if it ME or what BUT after fixing it i noticed the average mileage is between 19-17.5. I talked to FSWerks tuner (Raffi) about it he suggested I upgrade the fuel system. I suggested that may not help because its only has bolt-ons (header , went back to stock air factory) What is ya'lls take on it? I suggested getting it RE tuned, that would require me to flash it to factory by the dealer or replace the ECM (lost the original scanner in a flood) and re order a tuner. I have not asked Ol Turbo Tom about it yet.. SIDE NOTE: did ya'll know FSW will stop all emission tuning probably this year or 2?
