My friend has a 2007 Turbo S2000
It has the AEM EMS Gen2 (DBW Model)

There are 2 VSA lights. The triangle one which comes on when the VSA is off, and there is another one that says ''VSA''

He was driving the car at 9 psi without any problems
The other day, he increased the boost to 15psi. After that he started facing a problem

With VSA off (the triangle light is on) when he floors the gas at 3000-3500rpm at 3rd and 4th gears, at 6000rpm, the car starts cutting the power completely and the ''VSA'' light comes on. When he shuts off the car and starts it back again, the light goes off.
This doesn't happen when he floors it at 5000-6000 rpms.

Can this be happening because of a boost cut?

 

It's spinning??

 

If its boost cut you should see that your overboosting off your boost gauge. Also check aem and see where boost cut is set at.
