Does anyone know which tuner (superchips flashpaq or hypertech) will give the best performance for my 04 ram hemi.

 

I had the hypertech chip, didnt do **** for my truck, went out and bought the superchip reprogrammer, and that thing made a big difference, it changed the shift points, gave it 500 rpm's more and eliminated the top speed limiter, instead of the truck shutting down at 105 mph, damn thing shifts into 5th gear at 125 mph. And you can feel the difference in the get up and go that it has.
