The Weistec S63TU tune provides solid gains through out the entire powerband, with peak to peak gains of 50HP* and mid range gains of as much as 90HP* and 100lb-ft of torque!? 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 options available for race vehicles.? First is the "Burble".? The M4 GTS 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.

What does all this mean to you?? More power, sharper throttle response, and consistent performance with out sacrificing refinement.?
*Power gains vary based on model, modifications, fuel, and running conditions.
