How many RPMs at 60mph...

How many RPMs should I be turning at 60mph with stock tires, aw4, 3.55 rear end? Right now im at 2100 and that seems high to me.

Jeep sat in the driveway for about a week and the battery died. After I charged the battery it started ok, but almost stalled a few times at stop signs. Once it warmed up it was fine. Its not throwing any codes and has a new TPS and IAC. Maybe im just paranoid...

Sounds perfectly normal to me. That's not high at all. I run about 2500 at 65 with my current tire/gear combo. You're fine

Completely stock, and keeping it that way...

Its a jeep, not a race car jeeps arent meant to go 100+ mph, or even over 75 for that matter! It sounds fine to me too

Thank you, I knew it was the supercharged Pontiac Grand Prix I borrowed that was messing with my head.

This page will let you calculate your RPMs, or you can refer to the chart...

Using their formula, you should be at or around 2500 RPM in THIRD, not OD, and with the torque converter unlocked...
