I have been sidetracked, but have been meaning to update this thread. After determining that Oklahoma non ethanol 91 sucks balls. We went through the tune again and went with an E20 tune so I can blend E85 with the 91. This would allow flexibility just in case E85 isn’t available. I also decided to spring for the transmission tune since the COBB tune took forever to shift gears.
I am happy to report that I now am driving the truck like a 3 year old. Even the traction control system can’t keep up with the truck anymore. I agree with the poster above. 4A is a must with TC off. The truck is a wheel spin machine now.
I highly recommend the trans tune to tighten the shifts. It drives better than the COBB OEM+ and shifts faster.
You mean you have the Goose tune Trans shift update instead of the COBB trans? Is it that much of a diff, cause I have heard the COBB trans shif is spot on! what the diff with the Goose trans?
