Does anyone know a part number for the 180 degree thrmostat from a local parts store....such as napa, autozone, or advance? I put on my 3.5" pulley and getting a miss at high rpm, I've been busy so I haven't had time to look at it. So, I've just been taking it easy and keeping out of the boost as much as possible. Do you think it could have anything to do with the therostat? Was also thinking about getting some colder plugs and gapping them at .55, which brand do you all reccomend? Also, I guess while I'm doing this I'm gonna need to check fuel pressure and scan for kr...I think Lash said he has a scanner...maybe I could meet up with him one evening. And yes, I do have a FWI intake...so I'm guessing that isn't the cause of the miss.
