If it is factory supercharged (l67) then it doesn't have EGR.

yer shes factory .any idea on the hunting then?

Possible vacuum leak.

Mine used to hunt fairly bad until i put new spark plugs and a fuel filter in it. The hunting is hardly noticable now. I have a factory supercharged engine.

There's a vacuum hose that commonly dislodges itself on L67s. It's located underneath the throttle body and routes back to the firewall and around the back of the engine to a solenoid on the drivers side head. Just slip it back on if that's the one. Also check the vacuum hoses around the black thing (boost bypass actuator) between the charger and throttle body, especially the hose that does a 120degree bend going to the top of the actuator. These always degrade and leak over time. Any generic vac hose will do the trick as a replacement

Wat mods have you got? Wen I started modding my L67 it started to hunt/surge a bit wen I backed off and the tuner said it was the ecu cutting the fuel and it was fixed after the tune

got adjustable fuel reg, 10 psi pully .

From what I have read in the past, ditch the adjustable fuel reg and go back to standard.
