Spartan rough shifting

I recently decided to give the spartan tunes another shot. I changed to H&S awhile back and have been happy with it for awhile. I've done a bunch of reading and noticed not too long ago how spartan made all the tunes level 1 and free so I figured why not. So far I've tried out the 310 and 300 and the shifting is really rough. Do people actually daily drive their trucks on these tunes? I could have sworn in the threads about the 300 tune people said that it shifted like the 250 but had more power. Back when I had spartan and ran the 250 tune the shifting was H&S smooth and was an awesome daily tune. Is there any spartan tune thats comparable to the H&S HD300 as far as daily driving and not having the whole truck jolting from rough shifts like the high HP spartan tunes? Starting to think I jumped the gun on selling my H&S tuner before trying these out.

Are you doing a relearn process and giving the tunes a chance to learn? I've ridden in stock trucks with our tuning that have had the tunes loaded for awhile and the shifting is great in my opinion. Maybe I like a firmer shift point. Smooth shifting should be left to the lower files that won't burn up the clutches in your stock transmission.

So only the lower tunes have smooth shifting even after the relearn and giving it awhile? I understand the firm shifting might be better if you stomp on it, but whats the point of shifts like that just normally driving around? The H&S drove/shifted better than stock smooth as can be and felt like when you get on it they would firm up. I guess I'll give it some more time to drive around with but its pretty annoying to drive around on a daily basis with. I was really hoping I would like these tunes because I really like the dashdaq and its superior monitoring but I might have to go back to H&S if i will be stuck using low HP tunes.

Part throttle shifts will smooth out once the transmission has learned. Just give it some time.

I ran the 310 tune as my DD and loved the way it shifted. I did the relearn and i kept driving it the shifting got better on it.

I run the 210 Tow tune and its shifts settled out after a few miles (like 50 or so).
