Got the truck back from the exhaust shop, had them run 2.5" with no muffler. Drove it to work this morning (20 miles) and it did great. After I get a couple hundred miles on it, install boost and pyrometer guages I'll do some tweaking with the fuel screw and wategate to get a tad bit more fuel into the system.
After that I'll start looking into installing an intercooler.
Funny thing is, it will only run with the vacume hose disconnected from the EGR. When I have it connected it is exteremly hard to start and runs like crap and smokes badly once it does start. With the vacume hose disconnect, it starts and runs great. <img src="/forums/images/graemlins/confused.gif" alt="" />
