you could have the death flash... retards timing to stop pinging... there are threads here that will help you determine if you have it or not. if you do, you can get a programmer to liven it up some.

 

That baby might be flowing a bit too well. High way speeds with your gearing should still be around the 2k RPM range which in my opinion is still considered the "bottom end" of our power range. I know that all the Rams I've had that had duals sucked at this range. I got rid of my "duals" almost immediately with this 98 and can tell the difference. Some back pressure is a good thing. Keep in mind, I'm no expert, just stating what I have experienced with these trucks. Take care!

I parked on a very slight down grade andmy front wheels went over a 2" drop offon the parking lots black top.

When I tried to back up the truck wouldnt move! I had to pull up about 4 feet and get a run for it......
The truck just bogged like it couldnt get the rpm range to pull the load. It amazes me cause the truck has low miles and looks so good....

This is a 360 mind you....

 

Could the plenum gasket effect highway performance????????

 

Im thinking my CAT is plugged. I checkeda coupleplugs and they looked fine...Bosch plats...
Its going to have to go in the shop cause what ever it is seems beyound me.

 

did you cruch any exhaust products. if you did you would be restricking the flow. crawl under there and check it out. when you went off the edge you might have hit it. i doubt it tho on only a 2 inch drop. but you never know.
