About fan problems 300, STR8 2013 After 91 octane update

[Rogers767]

Hello, I try to write the English the best possible, my English is poor,

The problem is that the fan motors turns on more often than before the update, since I did the update to 91 octane now fan is passed more time on and high that is normal? before making the tune of 91 octane the range of fan motor engine is more silent and not start so many times and since I did the update the fan turns on too with more frequency than ever before, if I quit the 91 octane update and set the backup to a normal with out Intune update to a settings default , the motor fan works fine and normal.

so the other question is what is the best setting for save a gas, the str8 consume to much gasoline,
i appreciate the respond,

I make the update with Itune,
Thanks

the fans running more often are to keep the engine cooler.
T save fuel, get rid of the SRT and get a V6

Honestly, there is no way to see any big fuel savings on these high performance applications.

STR 6 CYL? that's exist?

no, he said to get rid of your SRT, and buy a V6 instead if you want economy

I recently purchased the InTune I-1000 and it worked before on tuning my F150 Ecoboost. Now after restoring it, I cannot tune it, showing a screen saying "Not supported." Moreover I registered it a dozen times trying to update it and the Intune will not register. In addition, I tried manually updating to 1r03h. How do I get it to tune this truck again and update tunes?
