Well I just got this about a week ago and I didn't get an owners manual so maybe you guys can help me since your owners as well.

On the 850 Platinum Edition I assume the button arrangement is the same. On the dash right of the driver side vent there is the light adjustment for the gauge cluster and then below that is a light button is that for the back lights? If that button is OFF but I have my lights turned on will that have my back lights on or does that switch have to be in the ON position. Also how do I make my light wipers work? Not sure if they do it on their own or not. Is there a place to turn up my PSI for the tubo. Not really trying to since it's the stock engine and not sure it can handle anymore than whatever stock is but wondering. That's about it. If anyone can answer all or any questions that'd be fantastic. Thanks!!

The light swich you are talking about is for the rear fog light. It won't affect your tail lights, brakelights, ect... if it is off. If activated it turns on break light on. The headlight wipers are activated when you use the front window washer.

 

You will not be able to add a boost controller to increase Turbo psi. The ECU will attempt to override boost controller. It is possible that ECU will get confused and use wrong fuel mapping. Start shopping for New exhaust with free-flow cat and upgraded ECU programming.
