I have an 03 wrx with no engine mods, I've been reading alot about cobb ap. being the thing to get before exhaust or any other mod. So I'm considering this purchase, but I wanted to know if this is hard to use? What exactly is it going to do? (yes I'm a noob) If I don't know what I'm doing, will you show me how for some beer and chicken? Can there be any downsides with the cobb ap? Thanks for your sarcasim, criticizim, mockery and help...

( Forgive me for paragraphing )

 

The Cobb AP is super easy to use. The hardest thing is waiting for the unit to marry to your car so that you can go drive it.
Make sure you follow the directions precisely and you will be fine. Since your stock you can run the CA stage 1 or stage 1 91 octane map with no problems.
It is a great mod and if you are looking to do mods to your engine it will help you a ton once you get a pro-tune.
Another benefit is it has a anti-theft system, which insurance companies, sometimes, will give you a discount for.

Yep...I agree. I bought mine and had Gruppe-S protune me. With a Bosal uppipe, Vishnu pulley, 3rd cat delete, stock downpipe, STI axleback and a COBB base map it made 180whp. After the Protune it was 200whp.

 

oh yeah, forgot to put the websites. The ones DomozitoLK posted were the ones I used. Mainly the cobb page. Hope it works out for you.
