I have a 2011, 103 SG. It runs like a freight train, but is still too lean with the "parade mode " coming on only after a couple of minutes idle and also a hint of backfire on decel. It's fitted with SE pipes but the rest is stock. Are there any plug and play fixes to richen it up a bit. I have no interest in doing anything else to the motor as far as go fast modifications go. regards, beagle.
