Weistec N55 ECU Tune

Stage 1:POWER GAIN* +75 HP TORQUE GAIN* +71 TQ Stage 2 (Race Exhaust Fitted): POWER GAIN* +96 HP TORQUE GAIN* +94 TQ The N55 vehicles are built very stout from the factory and respond beautifully to modifications.  While they have great performance right off the show room floor, it is just too hard to leave them untouched.  The Weistec N55 Tune provides solid gains throughout the entire powerband, with gains of +60WHP* and close to 60WTQ* torque!  This is on an otherwise 100% stock vehicle, including the air filters. In addition to the performance gains, there are a couple options available for race vehicles.  First is the "Burble".  This is best compared to that of the M4 GTS "burble" which comes from the factory with this in a mild form.  You can choose "Off" "Mild" or "Aggressive" for the "Burble".  Many seem to prefer "mild", but we gladly will let you choose based on your preference.
