Wondering if anyone has done any mods to their 1100cc Chery engine to get more power besides the Turbo, I was thinking of trying a High Flow Muffler in place of the Catalytic Convertor but there is a sensor on the C.C so I don't know if that would work?

I was thinking maybe a little power could be gained by going with a bigger Air Intake Sytem as well.

There is a real expensive ECM Chip that is available but from what I hear it doesn't increase powe much for the amount of money you will spend.

Any ideas, success stories would be appreciated
