Great..........

 

Great what?

 

I have seen on my AU flash has been a hotter running truck in general. Not much but enough so that I can see a difference in the temp guage in the dash. Mine sets right on the edge of the 200 mark of the guage.

Where it was quite a bit from the 200 mark before. Sure would be an area of improvement on these trucks would be to throw a serious set of guages in the dash

Fuel mileage best I can tell from all the towing I do is it went down but only by a little. I also can say that its affected my straight pipe setup in how the turbo comes in and starts to pump things up.

I have reworked the fine tuning on the straight pipe setup and seems to be better now. I will make a run tonight and will know more by the end of the day on Monday. More on what I have done with all this here

Post before mine reported worse mileage with AU flash. So great......

 

I just came from the dealer and had my truck updated, no codes or nothing and no problems figured I'd update id just in case, turnes out there were 4 updates, 1 TSB 18-037-07 rev a for a low line pressure transmission code, TSB 18-033-07 REV B so for those of you that had rapid response 07-021 it's not the same as far as i could tell from the w/o but I was there when it was getting updated the p/n ended with AU the only difference I have seen with this flash is so far is the WIF light now illuminates with the key on and goes off in about 3 sec, and I feel that the exhaust brake is stronger not much but it is stronger than before, and it respondes on and off quicker. the other two was for the sunroof and for the 4x4 axle disconnect.
now as far as the transmission it's kind of early to tell because at first the truck shifted rough and after 40 km of hard driving and bombing around town is now shift smoother than before the flash up shifting and down

 

I had the low line pressure code. They told me it was because I intalled a temp sender in the hot line and lost fluid. This is the first I've heard of that code.

 

my tranny seems to not shift as good as it did before the AU flash, not this IS ONLY when i have exhaust brake on and at LOW speed > 40mph. Also the truck seems to have even more hesitation or stumble at cruising speed. EX i am cruising at 65mph at steady throttle and i give it a little more throttle it kinda stumbles worse now. Seems to do it ALL the time now after the AU flash... Other then the two things i have listed here i am COMPLETELY in love with this truck.

 

After my flash I noticed that the tranny did not shift consistant hard shifts at first and then the softened up than hard again I also noticed that there is a hesitation between 1 to 2nd and when it shifts to fifth the engine revs higher like 300rpm more before the shift began than falls into gear.
I'm not sure if this was the tranny flash that caused this or the AU flash
