A base tune is just that, it will get it started and running. Probably have a few things deleted, security turned off, and not much changed in the actual tune performance wise. Go with an actual dyno tuner to get it done.
LS Current Performance Base Tune
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?
