Does it sound too good to be true? How much horsepower do you think you might get for $6.50? You spend $1000 and you might start getting close to a 35 HP gain.

thats what I thought, a buddy of mine swears by these scams. Thanks for clearing this up for me

thats the placebo effect

Man $6.50, that's one expensive resistor....

From what I hear the tornado....turbulator....swirler or whatever they call it is crap also.

yep! best way for an engine to get maximum airflow is just straight into the throttle body. No need for a swirling effect or whatever they claim -Mike-

If it sounds to good to be true than guess what... it is!

Thats a bunch of

Set my X-Cal up over the weekend. The 91 tune kicks a$$. I still think the Underdrive pulley is the best bang for the buck.
