Anyone know of a tuner that can send me an 0411 tuned to run my Gen III operated 422 LS3? Or should I try to start with a 6.0 Tune from an early vortec truck(DBC)? Trying to get a base tuned ECM to get the car to a tuner running and tuned correctly/completely so I can send the ECM to magnuson for further tuning for the TVS being installed. Thank you for any info/advice.
