HUGE Problem after tune

[ScarabEpic22]

Im away on vacation right now and am using a friends mac for internet, so cant look at the tunes. I would assume the different H0101 and H0104 values are designed to make small adjustments to the speedometer read out. But I cant say for sure. Plus, how are you measuring the performance differences? Butt dyno or actually using a Gtech or other device or dyno?

Here are the same files updated with the tire size properly set at 265/35R22 or 29.30" diameter. H0101 set to 94152.00 and H0104 set to 1462.58..

its ok no rush. yes here is pcm4less's tune it reads H0101 as 65724 and H0104 as 2637.4.

im measuring based on experience, my car is never this slow of the line making me have the stop on the acelerator even harder compare to pcmforless tune where i just press on the acelerator lightly and it shifts faster. My friend from the dealer agrees when he tested my truck.

you know what part of the problem was that I thought that GT4 was 3.42 instead is actually 3.73. thats y it was slow off the line. Ill check it out.

well i just did the 3tune1 update w/ no TM and the gear shift from 1>2 is weak, sounds like the engine was about to shut off. but when shifted from 2>3 I was halling ass! how can we adjust the shift from 1>2 and what do you guys recommend?

now the dealer (my friend's auto shop) told me that when you press on the accelerator it feels kind of heavy, meaning you have to press it harder to get the truck moving faster. How can we solve this problem???

I don't know about your vehicle... someone else will... post some logs.

i may be still new to this but how do you do that?

Im still waiting for a few minutes so I can fix your tune.

To log, open up the scan tool and read the tutorial on the scan tool. Then do some logging and post the files up.
