Ok, Thanks. I have only been running it up to 2500-3000. Does really good in that range, even with a 10 trailer and a 500 Rubicon on it. Have not had a need to take it anywhere near 5000. Even pulling up hills. It just goes.
Unless my tach is reading wrong, it idles right at 600 and I noticed that if im just easin through the gears, the little fuel economy shift light pops on around 1500 or so.
This is my first dodge truck. Got fresh paint and some body add ons and thats pretty much it. Shes old but she seems to run just fine. Still got the snap to her when I do get on it alittle. Thanks for the response.
