my gsr has not been tuned at this time, all it has is a base tune. I was wondering if my 3 wire a/f gauge would show a correct a/f and could i trust it teal i got it tuned. The gauge is a auto meter. All it shows is (lean,good,rich) So if it shows good to a little rich would it be fine to drive

All it can tell you is if it is richer or leaner than 14.7:1, since it uses the stock narrowband o2 sensor. The short answer is NO, it will not tell you anything useful for boost.

I wasted my money on one of those too. They are worthless for boost. If you are anything but full rich on that thing in boost your motor will blow up soon. I got an AEM uego wideband and couldn't be happier.
