Product Details
*All 2020 models require bench flashing at this time.
The Weistec S63TU F90 tune provides solid gains throughout the entire powerband, This is on a vehicle with stock exhaust and turbos. Additional upgrades will result in even more power.
In addition to the performance gains, there are a couple of options available for race vehicles. First is the "Burble". The S63TU comes from the factory with this in a mild form. You can choose "Off" "Mild" or "Aggressive" for the "Burble". Many seem to prefer aggressive, but we gladly will let you choose based on your preference. The other race vehicle option would be Catalyst Heating. On race vehicles, many times the catalysts are removed. In those cases, there is no need for the catalyst heating which would just be making excessive noise on a cold start of the race vehicle. If you have a race vehicle with the catalysts removed, Catalyst Heating can be disabled.
