What should I look to in order to see the best fuel economy? Just one by itself or both together? I've heard some folks say the extreme tunes give the best mileage if you stay out of the throttle and some say the puck gives the best.
Thanks

I wouldn't suggest the puck byitself if you dont have a EGT gauge, if you stay in it hard the temps get up to 1350(pre turbo) and still rising . The programmer on tow for instance will stay down a bit easier. You also have to rember to do the MPG calulations your self as the over head will be off with the tune or puck installed. The higher the tune the more it will be off.
