Nice increase in torque, car more urgent when pressed.
Michael,Skoda Octavia 1.9 Tdi
When I sold my A6 I traded my tunit for one to fit my wife's 1.9 TDi Automatic Skoda Octavia. the installation was straight forward although a little awkward because of the way Skoda clamps the leads. Once installed we started seeing a better than 10% improvement in milage on the VAG 1.9 TDi engine which on a long trip will often show in excess of 50MPG if driven carefully.
