Thanks for the info guys. 3,200 RPM seems to be okay for a V-6 at our typical highway speeds. yeah, I factured in our altitude as well to be a good portion of the problem. appreciate the help!

Yep. The OP lives in Salt Lake City, UT--4226 feet above sea level.
So, he has about a 13% loss in horsepower just due to the alititude and probably needs to be running at 2700 rpm to produce the same rear wheel horsepower as a sea level 2500 rpm.
As a result, he should regear an extra level lower than a sea level guy.
In the meantime, he should buy the Superships Flashpaq for $309 shipped from Northridge4x4, and using his 6 speed, stay in whatever gear keeps his rpm levels over 2500 on the highway/freeway.

Where did you get that quote? Was that just parts? If you are not worried about voiding your warranty, then the best bang for the buck is probably a super charger (Avenger).
Yes, where did you get that quote? If that is for the engine, parts and labor I am interested. The numbers I have are in the vicinity of $20K. where as the SC is closer to $6-7K.

Just look at the size and weight of the JK then compare that to the TJ. The 4:56 gears in my TJ, made all the difference in the world even with the automatic and 33's. Put 4:88 in JK with 35's and it still is FLAT especially from a start from a light (automatic) 1st gear lasts 5 feet, second foot to the floor to 50 all over fifty is tolerable much better than 3:73's still sucks in the mountains, how sad.
Will one of those Superchips Flash Pacq's help? And do you need to have a installed non-oem chip? Is that something else I need to buy...All I know that mini-van engine ain't gona last at those continual 4k-5k rpm shifts..I have been beat off the line by loaded dump trucks and a couple of cattle trucks. have to get tented windows OH the shame.....

I use the Unichip and love it. I hear only good things about the Superchip so either would be good. Dual exhaust, CAI, headers, bla bla bla, will only give you minimal HP boost. You probably won't even be able to tell a difference other then a better sound. If you want your jeep to sound meaner then right on , throw those headers and duals on. Just take caution with hearders, Burnsville Off Road told me that they have a tendency to melt a few things under the hood
You want more power, as everyone else has said. Regear
If you are running stock or smaller tires and don't plan to ever go bigger go with 4. 56s or 4.88s, 35" go with 5.13, 37" 5.38s

We installed a Flow Master Hush power inline with his Magna Flow - it sounds great. We''l have video and charts up soon in our thread.
