factory boost gauge

[skawty]

i know the stock boost gauge isnt extremely accurate but my boost gauge pegs out at 14psi as soon as it spools up. since ive been told the stock turbo setup is running 10-11 psi is this just a gross innacuracy on the gauges part, am i hitting high boost with a well built engine and got lucky...or is there simply a problem with the gauge or it just needs to be replaced with an aftermarket gauge....


also while im on the subject....when installing an aftermarket boost gauge. i dont need any extra wiring do it? cant you just pull the wire out of the back of the gauge cluster that connects to the factory gauge and hook it up to the aftermarket unit? and mount it somewhere?

never look at your stock 'boost' gauge again
its guessing what your manifold pressure is.

and no, you dont have to wire up an aftermarket boost gauge, but if youd like to see it in the night, then id recommend doing so.

If your referring to installing the gauge fully, then know you can not use what connects to the factory gauge. www.vfaq.com has a full install article just waiting for you
