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,
Stuart, Subaru Legacy 2.0TDI

I appreciate its early days but I thought I would let you know how pleased I am after Tuesday. Well more than pleased!!!
What was an excellent engine before has now been improved no end all round. I find myself wanting to drive it for no good reason other than to enjoy the released potential.
For example I had to go over to Leeds late tuesday night the M62 was quiet so the best way to describe it is "I drove it like i stole it". For the purposes of testing it out. I dont mean just high speeds fifth gear an all round caning.
When I got home around 150 miles later i did a double take mpg was showing 48.6.
Although my car gets well used doubt if I have ever given it the grief it had then so the mpg was a big surprise. Conservatively that's an increase of 6 or 7 mpg.
When I revert back to my "normal" mode I am sure the mpg will be even better.
As you could see I am no boy racer just a car enthusiast so not interested in top speed or 0 to 60 mph etc.
But at the other end of the scale as part of my testing i took it on a local industrial estate tonight and just leaving at tickover had it pottering around in third gear no problem even on a slight incline. No judder snatching etc. Third is long legged as well. Not something you do often but just shows the other side. Prior to the Tunit wouldnt do that at all.
So as you can see I am well pleased to say the least.
Obviously I will monitor the mpg over a full tank but i think I know what the result will be.
Thanks for the excellent all round service I received you have a good friendly set up there.
