I am located in the Bay Area Cali..Any good resources and mechanics out here to work on my 87 GN? Not too much of a wrencher just simple stuff like oil changes and what not..My GN needs a tune up. Just got it not to long ago but don't know much about em...I have a scanmaster and knock gauge. Bigger turbo and bigger injectors not installed on car yet. Turbo is a slightly used GT 6152 Turbo. Car also came with LS1 maf and translator already installed..I also have the extender chip in the car.The car runs OK but a little rich to me..I know it's not running to it's full potential...Anyway I need some help Thanks...Noobie to the TR scene...Thanks..
