Yeah we smoke and black out all lights for most makes and models. We can just do a very light smoke look all the way to black as black. Plus with the formula we made the darker you go will not block the light.
There were some problems with the way the air crosses the mass air meter, which affects timing and fueling.
The way the readings were scewed it cause the car to run rich with lower than normal timing values.
They are fixing the issue and we are suppose to get another test unit.
