[QUOTE=mxracer207;220834]I'm sorry and i stand corrected. they did modify the wastegate to pump more PSI, i think they put on a banks??? I'm sorry, i dont know much about this since im just getting into it....



waste gate ???? LLY , LBZ , LLM motors dont have "waste gates" they use varyible geometry turbos that change to amount of slip in the exhaust housing.

If your correct they most likely are tuning a LB7 truck 2001 ~2004 vintage motor or they are useing a old school turbo ....
