What would be the short list of mods to get my '09 MCCS (auto) up above 200 WHP? I'm rather disappointed at the paucity of mods out there for this model. Here is what I've gathered - please, somebody with more know-how tell me whether I'm on the right track:

1. Upgrade air filter (K&N)
2. Upgrade exhaust (Borla or similar cat back)
3. Upgrade cold air intake/intercooler upgrade
4. ECU mod/Unichip

Would these mods alone get me to the magic number? I wanted to get a 15% pulley, but that doesn't apply to this model. I'm not sure I'll gain much by swapping out the spark plugs for high performance ones. Finally, I just don't know what to think about the Plasma Direct Ignition coils - if somebody has the scoop on them please fill me in.

P.S. As for my choice of car, in a perfect world my wife would learn to drive a manual and I could've gotten a JCW. Alas, my world is far from perfect. Now my only hope is to modify the car that I have (and hope she doesn't notice too much...)

 

Im getting close (190whp), and I was tested on a dynamometer, which is (from what I have read) to be the most accurate dyno out there. I am extremely happy with what I have so far. About the only thing I have left will be an exhaust system. That should get me within spittin distance of 200 whp..

 

Not sure if we got an answer to this question, I'm looking at the same thing, modding to go fast!

 

Look at my post for the Magnaflow dual exhaust deal for $561.00 shipped, I just posted!!

 

JCW?

 

Best bang for the buck and HP would be intercooler, exhaust and RMW tune.
