So I just got my truck deleted with a 4" turbo back exhaust and a bullydog programmer. Just wondering if anybody has any info for me. My truck wont read boost air/fuel ratio or intake temperature. Also my fuel mileage seems to have gotten worst. Pre delete and tune it was running around 15L/100km now it runs around 20L/100km driving nice. Not sure if it makes a difference but it has been -42°C here for the past couple days. Any info would be great as to whether something is wrong or not.
