Just curious if same thing happened

I have the H&S XRT Pro on my truck and love it. A couple weeks ago I downloaded the new software which was 6.4.4 I believe and installed on the truck. It seems now my mileage has gone down a good mile and a half hand calculated it was at 14.2 city consistant and now 12.8, but my dash computer miles per gallon is within 3 tenths unlike before being 8 to 10 miles off. Also, as soon as I installed the new program the exterior temperature sensor is now off by 10 degrees. No big deal to me, but thought that was wierd. Just curious if anyone else had the same problem or it was just me?

The new software makes the computer very close to correct for miles per gallon. It is bumming a lot of people to see how bad there mileage really is again but atleast it is closer to the real mpg. I havent seen a issue with the temp sensor.

The miles gauge is nice having correct, but who in the world would trade mileage for the gauge being accurate. Makes no sense.
