Message: [QUOTE="Nic, post: 947318, member: 5508"] Well, I got the truck out of the shop finally and going. Loaded up IDP X-Street and this thing will do at a quarter throttle what my 6.0 ever could at WOT. The throttle is so touchy its crazy. Anything over a quarter throttle just slightly getting in it and shes sideways! Anyone else have this issue? LOL I also have the high idle thing going on and from what I read, it's because of the EGT sensors (rear sensor mainly?) not being plugged in and being tuned with a LW? Anyone else had communication failure codes? IDS wont read it, and the Live wire will program it ok, and see the gauges ok, but the EDGE CTS will not. Its really weird. Im guessing some sort of bad com between the OBD and the PCM? I tuned it before I left the shop and it acted funny. The turbos would kick on and off and then it tried to go into regen mode and I was like WTF. I know I just tuned this truck so why would that happen? It also threw a CEL for a throttle plate and I don't have one. Aaron told me it may be the older Live Wire that needs it to be plugged in, but every since I loaded the custom tune it hasn't thrown the throttle plate code or tried to go into regen, the turbos seem to act ok, but EGTs seem a little high. just getting up to speed and im in the 800s. Is this normal? Cruising about 5-600. Maybe one of the turbos isnt kicking on? I also thought the 59/71 would be louder than stock but they really arent. Doesnt seem to make enough noise to me, like something isnt working right. [/QUOTE]
