They were spedific about the v6, and had different numbers for below 98 for them they said the gain would only be 5-7 rwhp.
But you don't think a 45% is to drastic? The site guarantees that it won't affect battery charging but I'm buying the udp/balancer/belt second had (1000 miles on it) for $60 so I can barely pass it up.
I am not saying not to get the UDP. All I am saying is 17 Hp is outrageously high.
No bolt on will give you 17 HP. all of them combined maybe.
