No, I haven't. Been pretty busy with work, over 12k miles so far, since February. Sent from my iPhone using Tapatalk

I have Mickey Thompson Baja MTZ with an OD of 34.7. I did plug the programmer into the computer after I installed the program and it says that in order to update the programmer I have to return the truck to stock. Do I need to do that or call the support number to find out what I need to do? Oh, did you have to pull any fuses for the addons before flashing? OnStar, remote start, etc.?

Well yesterday was probably high 40s low 50s I was traveling at about 65mph registered on the speedo but I would venture to say about 70 actual Sent from my iPhone using Tapatalk

Thanks, I'll look into it Sent from my iPhone using Tapatalk

The dealer told me it was, they left the programmer in the truck for me, but i think it could be gradually off as my speed differs from speed trap signs, maybe I'll get it checked next time I'm in the dealer Sent from my iPhone using Tapatalk

You all gotta be running stock or something, this is mine, combination city highway but the trip A is with a 200 mile highway trip. Sent from my iPhone using Tapatalk

Im just going off my DIC and onstar tracking. But I will be tracking by actual average additionally from here on

So Ive been trying to keep an eye on my MPG since I bought the truck. I started two tanks out with E85 and averaged between 10 and 12mpg. I switched to 87 after that and havent gotten anything better than 16mpg. This is all a mix of city and highway, mostly highway and country roads at 55. I do realize that my oversize tires and my lift will affect my MPG but should it be that much lower than what I am seeing from guys on here with 20 and higher? I just started using Fuelly and will keep posting updates to my tracking. I would imagine that having the lift and large wheels/tires will prevent me from getting anything noticed by the dealer as far as a fault with the AFM or false claims of MPG ratings, so I dont plan on going that route but I do want to see if its normal or not compared to others. Edit: Ive currently got 2112 miles on her and my current lifetime is 11mpg

My main concern is drone. I haven't seen any videos or reviews with a 10 series installed though. I think the 70 would be a little too tame for my taste though. Sent from my iPhone using Tapatalk

I am looking at getting new exhaust as I want to hear that rumble from outside the truck. However I want to make sure I avoid getting a drone or excessive noise inside the truck. I am looking at getting the new Flowmaster Outlaw system with the 10 Series muffler. Has anyone tried this yet? Has anyone got videos of aftermarket installs that shows no drone but maintains that real truck sound outside. Thanks for the help in advance! http://www.flowmastermufflers.com/?page_id=451&partno=817689&make=48&year=2014&model=548&submodel=296&engine=2059&category=Exhaust%20Kits&kw=

I purchased my SLT new with a lift and oversize rubber, they included the programmer which they used to reprogram the speedo. I signed a contract with the warranty.

Im still curious if this or any other mod, exhaust, lifts, oversize tires/wheels voids the warranty? I dont think the lift or tires/wheels do, only cause I got it from the dealer with them installed. Do you just have to remove the aftermarket air filter before going to the dealer?
