Today my car was at Greg's because of my major hesitation problem and I'm happy to say that everything is fixed now. The number 6 cylinder was not firing at all so we replaced the injector. We also replaced the leaky boost hoses, fuel pressure regulator, fuel damper, all 6 spark plugs, fuel filter and the fuel lines. After Greg replaced all the parts, he suspected that my number 1 cylinder was weak so we decided to replaced the injecor. You guys will not believe this but Greg found an NA injector inside the cylinder!!!!! My car runs very strong and I even gained a .4kg/cm2 peak boost!!(my previous boost was at .74) Thanks Greg Jay
