  1. Are you 3 inch all the way back? Dual or Single?
  2. Hey peeps, I have a 15 GMC sierra 1500, it has the max tow package, with a 5.3, 6l80e, and 3.73 gears. What kind of fuel mileage are people getting with the same set up. I have some buddies that have similar rides, both 15 GMC's one has 3.08 gears a 5.3 with a speed and the other is 6.2 and an 8 speed with 3.42 they both get over 24 mpg. Anyone out there getting 19-20 on the highway like mine?
  3. this thing looks legit, thanks for the info.
  4. Where is the steering sensor located? Won't that disable the ABS and Traction control too? I would definitely need it on a switch.
  5. I know that I can turn off the stabilitrack but is there a way to make it stay off longer than 1 burn out? I have a supercharged truck and it's killing me that I have to stop and hold the button down for 10 seconds every time I want to go sideways.
  6. Hey guys thanks for the help, I did figure it out. It had 2 bad wires and and an arching coil on #8. I have since done a complete tune up with one step colder plugs and new coils all around. I did end up having it tuned this week by Stromberger Performance in Spokane, WA and HOLY #$%^! what a difference that made. Thanks for the help again.
  7. The scan tool I have is only picking up 1-4 or yes the front 4 cylinders. I can, with some certainty, move on a from a common ground issue then. It is only under load. Thanks. I will be doing what you suggest today. I am not sure what plugs are in it. I just got the truck and have put just over 1000 miles on it. The supercharger was installed by Davenport Motorsports in Calgary, AB. I know it does have MSD wires on it. With all this info you guys have given me, I am relived that is not mechanical, that was my assumption. Now I just got to go figure it out, thanks.
  8. Hello all, I am new to the site so if this is in the wrong place let me know. I have a 2015 GMC Sierra, I used the torque pro app to confirm that cylinders 1-4 are recording a misfire under load. It doesn't miss at idle or at cruise speeds. Is there something that links all 4 of these cylinders together in the engine harness, like a common ground or something like that. One more thing, I don't think it matters but, the engine is supercharged with a Magnuson TVS 1900, it has also had the DOD deleted out of the ECM. Any help would be awesome, thanks.
