The stock Gen III engine management system is one of the greatest EFI systems ever developed. GM could buy Holley with the money they spent developing their EFI.

Get the tuning right & You dont need it tuned ever again unless you change something & that's what HP Tuners & EFI Live is for.

Most/Good tuners dont charge full price after the first tune.
