I need to swap out the H&S mini maxx on a truck we have, just installed a BW 363sxe 80/.91ar last year.

Does Not perform well anymore, tried adjusting current tuner but not much luck on changing it.

Especially bad pulling a small trailer with a sxs through the mountains.

Looking for a tuner that will make driving much more pleasant and pulling sxs on road trips etc.

What's your input?

Thanks!
