Dyno: There's no doubt the unit delivers the goods. The Nissan Altima baselined at a measly 115 whp. At 5 psi, the ESC pushed output to 177 whp, and at 8 psi peak power jumped to 208 whp. At some points in the power curve, the ESC generated a 100-percent gain in power. Torque also dramatically increased. So 208 at the tires pushes this sedate Altima to a new level. Remember: it's an automatic.
