The 500-600 increase in rpm's is what I'm hesitant about. I do most of my driving above 50mph, mostly on the Highway from 70-90, so I would be burning up more fuel which is not good.

I would very much like to keep the 3.54 gearing because of this, I think with the ECUtune TCU it would fix any "problems" with over heating right? Also if I got a valve body upgrade it would definitely fix the problems with the transmission right? with an external filter and cooler it should last at least another 120,000 miles at 84,000. Am I correct?
