Best mods for money and performance

[jsbihn]

Thats fyr,
I guess what I am also looking for is people's own research on the parts too.
See, I could research all that, which I know about the mentioned but it is about what people have seen on their end to be the best.

(ie. like some people say get K&N for a car you will see 10 hp gain, but you get it and everyone only sees 5 hp - yet if they get say another company system, those people actually have seen 10 hp or say if some people build their own system they see 5-7 hp increase for half the price of a bought system. of course this is just examples of a fictitious car and system)

and as for a s/c ummm nope that is way out there. remember this is a daily driver. my vette and m3 (which are the weekend cars) get the cash, this gets the what ever is left in my wallet :-p
