310 Low response question

[Black Beauty]

I had my truck on the regular 310 tune and it was hard to drive. especially trying to back out of a gravel driveway. I barlely push on the pedal and it would spin the tires. So I thought id give the 310 low response a try. Ive never heard you guys talk about it. My question is, what is the difference between the two? I know its less response of course, but is it just less touchy. or is there less HP? is my quartar mile times gonna be difference between the two tunes? Thanks!

no HP difference, just less throttle response.

Watch the MFDSD parameter and you'll see the fuel doesn't get chopped off when you let off the throttle like it does with the regular 310. But I've always wondered about the difference in the power myself.

Im glad you mentioned that. As soon as I took it for a test drive after loadin up the 310 less response I noticed that when I let off the throttle, it doesnt cut off the fuel immediatly. It lunges forward for a second or two with no throttle applied. I dont really like that

The low response makes for pulling a trailer much nicer than the regular 310 for that reason but I hear you; when I want to start coasting I want it now not in a second or two later

No horsepower difference like stated above. Throttle response is the only factor between the two that is different. The low response tune does not have as touchy of a throttle response which prevents the truck from bucking at certain RPM's or when your foot can't stay steady on the pedal. The regular is basically an all out race version. The low response is a more friendly daily driver tune.

One thing I noticed while in the 310 low response is that when it shifts from 2cd to 3rd and 3rd to 4th it will rev before it shifts. Like when your drving a manual and you give it throttle before you let the clutch out all the way....thats driving easy. harder driving, it doesnt do that....

Another concern I have it when the 275 is loaded. When Im 3/4 throttle going into 3rd gear it will shift hard and go right back to 2cd. its like its trying to go to 3rd but its not letting it. it will do this 3 or 4 times then it will finally get into 3rd...dont know what the deal is with that....

Im now driving the 210 regluar tune. love it. not problems at all with that. shifts great
