Hey guys, I need some advice whenever I'm towing with my truck its just not giving me its full. It struggles up hills, and I'm just not able to keep good speed either, and this is while ted exhaust,owing th bobcat. I've got a modified exhaust, but what tuners or upgrades would y'all reccomend? I don't want a tuner that reprograms my truck, I would prefer somthing that works with it.
Thanks guys
Tyler.

 

They all pretty much have to adjust your fueling and sometimes timing. I have a smarty and it can do both. It's great and not too extreme. But running a programmer or chip you'll need an egt gauge especially towing.

 

What kind of programmer or chip would you reccomend? And what's the difference between the two?
Thanks!
