Ok I encountered a little problem. Started the truck up this evening to go to work and had a cel with a deep exhaust note. Wasn't thinking but cleared the cel without getting the number. After clearing the cel the exhaust note got deeper. Drove a few blocks and could hear the turbo really spooling. Looked at the Spartan and was reading around 40psi at maybe half throttle. at idle I had a negative boost pressure at idle. At a little more throttle the boost reading was around 60! Power was reduced off low end as well. Looked over the engine bay and nothing seemed to be out of place. All boots were on. I dont know if im crazy but i thought the down pipe looked a little loose but no soot was present or smoke. I forgot to mention the cel was exhaust related. After the truck idled a little bit the loud low exhaust note went away and I had a 1-2 psi boost at idle which is normal for my truck. Any ideas? With the wind chill its around 8 degrees or so here. Truck has all basic mods, Spartan 310, and an elite 71mm.
