LS Current Performance Base Tune

1868 Views 14 Replies 7 Participants Last post by  EZA
I have a 5.7 LS1 with a Current Performance ECU/harness. No big power adding mods have been made to the engine. I don't know a whole lot about tuning so I don't know how much of a difference a professional tune would make compared to the base tune the ECU came loaded with. Does anyone have any experience with this? Should I leave the base tune or would it be worth the $300+ to get it tuned?

I picked up 75hp...I'm sure there is more waiting to be unleashed. It's running pretty rich right now so I'm goin g to take it back for a few adjustments.
Well....I have no reason to lie. I'll see if I can find thee dyno sheets.
