2005-2009 4.7L GX470/Overland Torque Tune (Naturally Aspirated)

The cost for tuning the GX470 (2005-2009) with the Overland Torque Tune (OTT) is $460. You can expect instant throttle response, greater low to mid-range in torque, a much linear power-band, smoother shifting and greatly reduced gear hunting. The OTT tune works well for both on road and off-road capabilities. Tuning process can take between 30-40mins in length. Any mod upgrades that come with added weight we can adjust throttle as needed to accommodate the new weight at no additional cost so long as you own your GX470.

We don't take payment upon test drive so you can have the opportunity to feel the OTT tune with your GX470 to make a determination whether it is worth your investment. Not impressed with the performance results?  No worries, we’ll retune your GX470 back to stock and not a payment taken. Even if you were happy about the results, we still offer a 30-day guarantee anytime within that timeframe you're not impressed with the performance results, we do offer a full refund minus a licensing fee ($100).
