Well I decided to return my throttle response to STOCK and I kept Auto Start/Stop & DFM Turned off through Pulsar. Still was getting Avg 8.5 to 10MPG (City Driving Of course). So After a few days of not seeing a improvement, I turned DFM back on and still left the auto start stop off. Now my MPG went back to Avg 11MPG. I just feel like I'm supposed to get better MPG with having a air intake (Which advertises it increases MPG by 3 supposedly). I did throw some Octane Booster to see if helps but not seeing much of a difference other than my normal MPG with Stock Throttle/DFM ON. Just crazy to see other people in the internet saying they're getting 16/20MPG with similar mods and I'm getting the worst of it. Maybe Sparkplugs?

Hey, just wondering if anyone experienced bad MPG from a 2021 Silverado Traillboss 6.2L using the Pulsar LT? I have a these modifications on the truck: Closed Box Air Intake from Volant Performance Borla S-Type Cat Back Exhaust system (Dual Pipe Exit) Before installing the Pulsar LT to disable the Auto Start/Stop & DFM. I was averaging about 10-13MPG (Roughly 11.0 MPG AVG). But soon as I install this Pulsar, I can't get any better MPG than 9.5MPG. I don't drive as aggressive and I don't got any performance modifications aside from the exhaust/intake. Am I doing something wrong here or possibly something wrong with my truck? I do run Premium Fuel (93 Octane) since its a 6.2L. And Throttle response is set at Level 2. Also Keep in mind, I do drive more city then highway, but I don't think my MPG should be this BAD compared to highway.
