Sound better? TBE

Faster? Engine management. Some of us prefer Cobb, others have their favorites but any is a huge boost over stock (even better with a TBE)

That's right.

A downpipe is the first thing I would change. A full turbo back would be better, but at least the downpipe.

Engine management is a good idea, but you won't see as much gains on a stock car. Plus, the downpipe gives more "butt dyno" gains than engine management does.

This might sound stupid but...
What does removing the intake silencer do? and what are the benefits?

And the BOV is a waste if you are looking for performance. Helix catless downpipe, catback of your choice, and an AP and you are right around 1500 dollars. Just my .02

Engine management is good for 20-30 HP, that would be my first performance mod (and it was). THere is NO OTHER ONE SINGLE mod that can get you those kind of numbers.

Engine management CAN be good for those kinds of numbers. But, it requires tuning. Just throwing it on there won't get that kind of gains. A downpipe will.

you can do engine managment first and tune a completly stock car. but i cant see you netting 30whp more with the stock exhaust or at least the up pipe. To make power you raise boost then add fuel ect.. but you cant raise boost with the stock up pipe because of the cat.. high egts will cause the cat to break apart into the turbo..then you have to spend money to get a new turbo not worth it.

Imo just get a full turbo back.. then get an up pipe utec/ dyno tune and you will have a nice amount of power. as soon as you start playing with boost and ect you will need at least an boost and egt gauge. i would go with a electric gauges from experince my manual guages were way off.

as soon as you upgrade to a bigger turbo thats where you will see a big increase in power.. and a big increase in the amount of money you have to spend to ..

If you can wait and save up some money, a UTEC/TBE/and Uppipe make quite a killer combo. Huge improvement from stock, you can really feel it. I've missed those drastic changes and I'm stuck with guessing whether I can tell the difference when I add parts now.

256 WHP on Mustang dyno that measures Stockers at 167.

I'm leaning towards the intake after hearing cosmo's ride. You really miss out on the syphony under your hood. Granted it prob isn't a serious power mod but prob in your pricerange if you're looking at ECU/uppipe/TBE at one shot

He said sound and speed.
BOV and Intake Mod are a pretty good sound mod to me...
TBE is a great starter speed mod and definately opens up the boxer rumble...

If i could only do one mod a TBE would be my pick for the HP gains and the SOUND!
