Hypertech tuning messing with
</P>
I just installed a Volumizer made be Hypertech in me 2003 Ram diesel. It got 3 steps. Stock, + 60hp and + 100 hp. The power increased allright, but I can`t feel any difference between the steps. And the engine is jumping a bit up and down at steady engine speed. This is mounted by the dealer, so I`m going to give them hell. But I would like to get in touch with someone that got some experience or knowledge about this product and other power products.</P>
Can anyone help me.........</P>
