This is prob the best you can do...

There are other companies that offer this also. Just plugs into the OBD II and in a few minutes it's programmed.

 

Get an ECU tune, the most bang for your buck

 

Do not remove the screen on the MAF. You heard wrong. It will not increase your power. What it will increase is the chance to truly damage your engine.

So do not do it.

1. What is your budget?

2. What is your Hp goal?

3. Are you N/A or turboed?

Lets start with the basics first. Then move on.

 

YES TURBO, I HAVE A K/N FILTER TO INSTALL TONIGHT. REALISTIC UNDER 1000.00 AND 15 HP OR ATLEAST SOMETHING I CAN FEEL

 

WELL INSTALLED FILTER TEST DROVE CAR AND FELT A BIT MORE POWER.MONGO LIKE, MONGO WANT MORE,MONGO NEED GET CREDIT CARD FROM WIFE AND BUY MORE


OH YEAH CAR IS FWD

 

Your best bet is the PPC ECU upgrade.

 

what would be better a new down pipe w cat or a cat back system how hard is it to install and which would be best to do?

 

Witha turbo engine,a bigger downpipe should give you more than the cat-back. I would get both to be honest, but if you have to choose one, I would go with the downpipe.

I guess it depends how mechanically inclined you are. A friend of mine is a mechanic, and one of the bolts from the dp to the turbo housing broke off requireing it to be drilled out. Luckilly he had the tools to do it (which I don't) and it was still a PITA, so anything is possible.
