I have recently installed a turbo and am having some issues with it not boosting past 4lbs. I am running a basic set-up with 12:1 fmu, 255 Walbro on stock injectors. It was running rough for the first day or two so I checked the gap on the plugs and set them to .034. Once I did that it boosted to 7lbs and was running awesome, no hesitations or anything. The exhaust manifold gasket started to leak(I should have known since it had a little kink in it from the start). I replaced that as well as the gasket for the manifold to turbo gasket. It is no longer leaking yet I am still only getting to about 4lbs of boost and it stutters. I have checked for leaks throughout the intercooler piping and everything is tight. The top vent tube for the wastegate was hitting the hood and after reading about this in the forums I found it is not necessary to have it on there. Any idea's would help.
thanks
Justin
