Douglas,VW Passat 2.0 TDI

I have had a tunit unit fitted to my VW Passat estate now for about 7 months, and it's great. Performance and fuel economy as well. What more could you ask for. Well Done Tunit, and Best Wishes for the new Year. I hope your sales of tunit units rocket so fast that you can't keep up with demand.

Happy Christmas to all.

Hi Dan, Have left it a while to thoroughly check my findings, and am very pleased - this last tweak, along wih the K & N filter means I am now locally on 44 to 46MPG, on a run 57 to 60MPG, the torque does not seem to be affected for it still accelerates in high gears from 1200RPM, and lots of torque by 1500RPM, but the even more surprising result over two longish but in traffic journeys tugging my 1500kg caravan gave me 36MPG, excellent. All on a tank top fill basis so no computer optimism included! This setting certainly suits the engine. Thanks and regards,
