Got mine off EBAY *shudders* for $20
I do notice it being a little more torque'y
and my lights seem brighter/blue'r
And Sound system is DEFF louder
However, My lights STILL dim when I crank this beeyatch up..Bugs tha shit out of me..I dont know what else to do
I have a Red top Optima
I have a CAP
I now have grounding kit
I have high gauge wires..
(one sub, one 600W amp)
Dunno but all in all the kit was worth it...Install is easy for the most part, it didnt come with instructions but yet again trust ol Ecelica.com saved the day..Even though I think the pics of the install were from an older GTS, I still got by...
AAAANND IM SPENT
