How To Add Partial Throttle Torque To 5.9
#11
May be silly but check that there's no slack in your throttle cable. Also you're comparing a 2wd truck to a 4wd one, weight factors in a lot. My dad has a 91 Dakota 2wd with a 170hp pre-Magnum motor and 3.55's and I have always found the throttle touchy, it jumps off the line much like a newer car does. It feels like it moves the truck more easily compared to mine even with new 4.56 gears. I have always found I have to lean into the throttle more on my 97 4x4, however, it's almost a ton heavier so that factors in a lot. Curious about obtaining more responsive throttle as well. Harland Sharp 1.7's would be a good bolt on if you are not looking to break the bank or do a complete tear down.

I didn't misunderstand, I just stated my point poorly. My truck makes plenty of low and mid range power, for a stock engine. It doesn't take much pedal at all to get it moving at a pretty good rate of acceleration. If you're having to go to half throttle to feel like it's getting along, something is wrong.

Heres the 46rh/re numbers
1 2 3 4 R
2.45 1.45 1.00 0.69 2.35
GM 4l60e
1 2 3 4 R
3.059 1.625 1.000 0.696 2.29
even with the 2.45 first my 2500 with 5.9 v8 accelerates great and not even part throttle and 3.55 rear, around town i barely go over 2200 rpm taking off and before the truck shifts. Being that your truck is an 01 you have the deathflash from the factory, maybe thats why you have to push the pedal down more to accelerate? check your plenum replace if need be and get a superchips, that will get rid of the deathflash, and should help with part throttle acceleration.

This is what ive always said. imo are transmissions are geared more for being in cars. sure our trucks accelerate fine with or without a trailer or load but the chevy is going to do it easier because of the numerically higher first and second gear, but thats about all the 4l60e has going for it.

Your numbers are off:
The Silverado 5.7 in 1991 had only 210 hp at 4k and 300 lbs/ft at 2800 rpms. The 5.7 never had 350 lb/ft. It peaked with 330 in 1996. Your Ram numbers are correct.
There are several things to help mid throttle performance from intake to fuel to exhaust. Do some searching both here and Google and you will read for a year. Also, little things like tire size/air, outside/intake temp, octane/quality of gas, etc. all play a part. If that old chebby is beating you, there's most definitely something amiss.

I had thought about the weight difference and such, but the strange thing is, a few years ago I was driving my step father's 1998 2wd Ram with a 5.9 and ended up running against a guy who had a 1994 Silverado Z71 with a 5.7. So it's the opposite of our scenario here. The chevy was 4wd and the ram was 2wd. Sadly, the chevy won that race by a decent margin as well. The chevy's in both scenarios had ~70k more miles than the dodges.
