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.

Both latest vehicles have benefited greatly in terms of performance and fuel saving and I have had several on the different cars i have owned. Would always recommend.
