As far is my opinion, I think that is about as much you can get without a turbo upgrade or running the fuel system with E-85(ethanol) or doing a water/alcohol/meth injection).
I don't know who will come up with a set of cams but I think the day they release some cams it will probably cost like $2000.


440hp is a great HP number to leave the car alone. I would say don't touch the catback, just do tune, downpipe and air filters and call it a day.

Carlsson already beat this with their CLA 45 mods. They're up to 450hp and it's backed by Carlsson's warranty.

There's definitely more play room.

That's great. Finally someone has unlocked the ECU. Hopefully everyone else will be able to now as well.

I was just about to buy a piggyback, but this makes me want to wait a bit.
