When I first got the car a month ago every time I stomped on the gas it responded and the car took off. Weee! Couple of days ago I have a friend in the car and I’m showing off how well it accelerates off the line. I do as usual from a dead stop I hit the accelerator and the car starts to go then there’s a momentary lose of forward momentum then the car revs again and I’m off. ?? What gives?? Its done it a few times. Its like the power to the wheels is being nicked for just a second. If I turn the VSA on or off I can never figure that out. When the exclamation point in the instrument cluster is lit up I don’t have this problem. Any idea what could be happening????

P.S. This is not a traction issue I'm 100% sure of that.

 

That's because your VSA is on.

 

when you're exclamation mark is lit up your VSA is toggled "off". The VSA when on (standard setting, no ! light), your ecu will cut engine power if it detects slippage in one or more of your wheels. With off the line WOT launchs, this is highly possible, until the car regains proper traction and then will re-engage at full power.

Next time you want to show off, turn the VSA off, meaning the ! light stays on.

 

ah!!! thank you
