      Do you have LS tunes available to send?

      We do not have any LS tunes for our BluePrint LS engines that we send out.

      If your engine was purchased with the GM ECU/Harness it has been loaded with a start-up tune. LS engines still require professional level tuning to maintain warranty. 

       

      If your engine was purchased with the BluePrint ECU/Harness, it has been fully tested, calibrated, locked ECU, and optimized for this specific engine.
