I am shocked. I honestly was a bit skeptical how much a difference a piggyback ECU would truly make, but I can definitely feel the torque now. This is how it should have come from the factory.
I do have extra mods that others do not have, like the HG Motorsports intake, engine mount upgrade, muffler delete, etc. so my results may differ... However, my GLA250 is a LOT more fun now! >
I would now believe the dyno numbers Carlssön has shown on youtube. Definitely making over 300ft/lbs torque now.
I also want to let you know, that I will be doing a catless downpipe with a new tune eventually, so I won't feel bad about the possibility of selling this to another forum member someday, it really does WORK!
