Blackbear tune

Hey guys, yes I plan to post real mpg numbers in the next few weeks. How I plan to do this is simple. I tested the truck on a few roads before I got the tune. I did record some mpgs at that time. After another fill up and driving some, I will replicate what I did before on those same roads. So I already have my set control numbers and soon I will have some test numbers. I will then put it together for u guys and provide an update under a new post. I already recorded in how it was done originally so this test should be very close to accurate as can be within a small margins due to weather if any. Otherwise the electric fan issue has been on my mind before. But a GM mechanic and a few Others have advised me not to do it. There are just is so many reasons for and against it. So if anybody here does it then post your test and progres with it. I for one am interested, I just replaced my clutch fan the other day...it failed when we were up in NC. Truck got warm but no over heating... We left early in the am for the ride home since we would hit the mountains when the temp outside was colder.... The new fan clutch is made for towing so it turns most of the time. But living here in Florida when everything melts due to sun and humidity, I don't mind that it's doing the job it's designed to do....
