If anyone has lower gears what rpm's are you seeing at 75mph? The reason im asking is because the more i drive my truck the more i notice that it falls on its face when shifting into 2nd during normal driving. Im thinking gears and H/O cams will fix this.

do you have superchips?

Yup. And the TM

you should try my shift schedule. gets the rpm's up in 1st gear so it does not fall flat so much on the 1-2 shift.

I don't have that issue. I'm using the superchips performance tune with stock shift echedule.

i know jusyjay in the ram section was selling his 3.92's like 6 months ago, i was going to buy them but didnt have the doh. he might still have them.

running 3.92's...75mph puts me around 2100-2200rpm.

I think that my truck is at about 2400 rpms @ 75 mph with 4.10 gears.

4.10 dont really know, I set the cruise at 60 mph on the highway, dont like the truck screaming that much, but i will tell you this, truck never falls flat on a heavy foot and sometimes catches 2nd when shifting

Im thinkin this is my next performance part.
