TTS Supercharged Toyota Aygo running a Rotrex c15-60 @ 0.9Bar boost. Standard engine, TTS custom exhaust system. Power and torque more than doubled over the stock engine and exhaust.
Considering the engine is an inline 3 bangers, engine movement is inevitable. Bear in mind that 3 bangers are terribly balanced. Furthermore, the additional supercharger will wiggle the engine even more. Yet the movement on this supercharged 3 cyl isn't " excessive", since it isn't worse than that of the N/A version of the engine. I believe it is a remapped stock ECU, but decat exhaust.
