I haven't posted in a while due to ongoing deployements but here goes. I recently tore down my motor and installed: Pro torker heads, cam, high volume fuel pump, GMPP intake and 46mm complete kit from xtremefi. After putting it all back together the truck fired right up and ran fine except for a high idle. After months of troubleshooting I came across another xtremefi consumer who had the same problem. Turns out the throttle body was leaking air past the blades due to bad bore. All I know is that when I put my stock TB back on I had no problems. This is after resetting my IAC base idle, replacing my IAC, resetting the throttle blades in the TB etc... To say the least extremefi's customer service is considerably less than desirable. Just wanted to get this out there in case someone is leaning that way. I would go with someone reputable. Missle
