Perfomance chip/ecu

So i was just wondering if any one had any noticeable performance gains using those jet chips i was thinking of picking one up but so far hear its probably not worth the dough. Has anyone swaped out their ecu for a mopar performance ecu? or how about the hypertech programmers..

go programer there around 380 or so a bit much but one of the best bangs for your buck around.

I have a performance ecu from dodge, it came with the truck it is a limited edition. It adds an additional 30hp and 45ft lbs of torque. Dyno tested
