I'm thinking I might get a tune on my 4.4 engine. There's a place called ecu tuning group http://www.ecutuninggroup.com I came across. They said a tune would give me an additional 30hp and 25 ft lbs tq.
Complete bullshet - just give that $ to a charity.
There’s no real tune for naturally aspirated engines like these to honestly increase the output like that.
The supercharged models and especially the tdi would have lots of potential though.
