Hi,

I’m currently driving an automatic 2017 5.0 with a roush cold air intake, roush full active exhaust and own a SCT X4 tuner with a Standard 93 octane tune but it seems to be riding a little rough (especially when downshifting, mostly into second gear) Any suggestions what I could change as far as a tune goes? I have never messed with the tuner before.
Thanks!

Can you explain "riding a little rough" in a little more detail? Some of our automatic friends may be able to tell you if the caned SCT tunes effect trans shift points or pressures. Or, you could call SCT and talk to them, they have always been very helpful when I have called.

It just jerks forward really hard when downshifting. Now I know the 2017 models don’t revmatch but it wasn’t this aggressive before the tune. I will try calling them as well, thanks!
