Getting More Power/Better Performance from the '05 Mustang

Anyone have ideas for getting more power out of the GT's V8? I plan to add a supercharger in the no-so-distant future, but I'd appreciate any expert advice on adjustments I can do myself (or have a shop do for me) in the mean time.

I'm a bit of a novice at this kind of thing and a first time Mustang owner so please, type slowly and use small words.

Small things to do for a power gain would be a K&N air filter and a cat-back exhaust. That would open up the airflow a bunch and would not void your warranty. I also thought I read someone opened up the air box to make for less restrictive air flow into the inlet and throttle body etc.

Yeah, there is like a paper element inside the intake track. I would say a CAI, and catback. BTW, a K&N filter will void your warranty on the MAF. Any filter that contains oil will. Seen it many times.

Really? . I was planning on adding that. What about Flow-Masters?

Is that something new? I threw a K & N in my 98 on my way home when I bought the thing new and it didnt void my warranty

yea, I also never knew that the K&N voided any warranty

I always heard they were allowed too.

A K&N won't void your warranty. Just don't overdue the oil after you clean them.

WRONG. Ford sells K&N filters, both rebadged and original.

Actually, you all are wrong. lol. I WORK at Ford, and I know what will and what won't. Yes, if you over oil it and there is oil on the MAF element, and you bring it in for a Check Engine Light and it's a bad MAF because of oil from the K&N, they will not replace the MAF under warranty. It will not void any other part of the warranty, just the MAF.

that would be considered abuse of the part (MAF) IMO. The K&N filter itself can't void the warranty.

No, it won't. But if there is oil on the MAF it will. I wasn't clear enough I guess. The filter itself will not void the warranty, but if you have MAF problems, and there is any sign of oil on the element, it's voided.
