chevy0128

i have a 2001 z28 with just aa few bolt ons .its my dd. ...headers intake exahust...the main reason for me tuning is to get rid of a damn spark knock from 4500 to 6k rpm under WOT. SO should i go with a street tune or a dyno tune?

Always going to have the best tune on a Dyno. There really is no substitute for a Dyno-Tune. If you can have one done, go that route.
