Is this all?
The best that I can deduct from all I've read is that mufflers and K&N's are about it as far as you can go with these V6's. $350 for maybe 5HP 
just isn't cost effective. If anyone knows of something different let me know.

K & Ns have no real proven HP. The best your gonna do is headers, exhaust, ECU tune. That will get you a solid 30hp. If you have a 3.0 its tough, the 3.5 is much better and responds better. These cars are cosmetic mods mainly, motor is limited. Brabus does a 4.0 overhaul for like 8k thats 330 HP if you have the $$$. You can also do motor swaps but thats big $$$

ECU tune + exhaust and K&N filters you are looking about 300hp +
Take advantage of the powerchip special they have a new tune that offer more HP

When Ford produced the Cobra they placed a snout on the end of the air box about 3" in dia. and ~8" long. This was done to meet EPA fleet sound requirements. By simply removing the air box and adding a conical K&N air filter we picked up 60 RWHP. Opening the exhaust netted 35 to 40 RWHP. With just a tune and the other 2 mods I netted a total of 484 RWHP on the dyno. For those who don't know about the Terminator the engines were hand built with forged crank, Manley rods, forged pistons, with a Eaton super charger on top. You can't pull any air through a 3" opening.

you'll get 20 in a 350, not a 300. its more like 10hp from what I read. I did the tune on my new 350 and notice a difference. I havent run it yet to actually clock it but its something better than stock
