Vortec 8100 / 8.1L / 496cid Computer ECU / ECM TuningPlease note: Raylar does not offer computer tuning for the Vortec 8.1L / 496 MAG engine.
Below are a list of marine and street tuning companies that can handle your computer / pcm tuning needs. 2001-2009 Vortec equipped trucks use the same computer as a 1997-2001 Corvette (LS1). If you are having difficulty finding a tuner who can handle the application, explain this to them and they should be able to figure it out. Raylar is not responsible for any work performed by the tuners listed below, but our clients have had good results and recommended them to us.
