Is it worth is. I was in my friends CL-S last night, and I thought it looked awesome. You can change the display.....blah...blah....blah....Does it serve a purpose/how much installed/where to put it if I get it.
(pics if possible)

 

i started looking in to it too, but i heard it's not worth it. It enables u to engage the Vetc at 4000 instead of 4500. Im not sure if it changes ur air/fuel ratio. Any one else know more????i think it's a waste. Has any heard about a chip for our car or is the Vetc Controler a replacement for the chip?

 

not worth it...I got it for my CL...I have it on my TL now..it looks cool, but if you're not running NOS or forced induction you don't need it...
professionaly tuned on a dyno I got a whopping 3hp and 2ft lbs...

 

I looks cool......but if it is usless, I'm not gonna waste $400-$500 on it
