    • GL550 dyno tune by OE Tuning - +18 whp on 91 octane

      OE Tuning recently tuned a GL550 in Northern California at 034 Motorsport. The GL550 is all wheel drive so keep in mind these gains are at all 4 wheels. Also, this tuning was done on 91 octane pump gas. Peak gains of 18 wheel horsepower and 20 wheel torque were seen. The dyno used is a dynomite.
