engine tuning

so what i feared in buying a 6 cyl NA motor has come true.....pick up sucks unless u put your foot down......situations of merging on freeway or slowing and having to speed up quickly.......the tach needle jumps around finding gear to make it move....i miss my 6 liter 10 yr old yukon in that respect

so that being said who has tuned/chipped their 3.5l.....i assume this engine makes its rounds in other mopars....there must something out there....anyone know or have experience to get some more power out from this engine
