After a little wait I eventually got my chip weheee
Right after I put it in I went round the corner to the local by-pass and was surprised at how much more torque there seems to be. I was going to overtake so put it in sports moder and floored it and shot off so quickly I nearly buried it in the guy in front..

Generally though there is a noticable increase in torque between 2-3000rpm which means it holds a higher gear a bit longer. Also on steep hills you can really feel it, and when its about 3500rpm the pull is really good.
The engine does seem a bit rougher though with a definite lumpy idle (compared to before), and when you floor it it sort of roars and screams (albeit a bit of a muffled) - a decent exhaust would sound awesum.
It's difficult to tell, especially on an auto, but there feels like it's added about 5-10% to the torque overall, and the torque curve feels as flat as before which I like. Would love to get it on a dyno.
I've only done about 200 miles so far and am hoping it will improve the mpg a bit, but I won't know for sure for another few weeks but I'll let y'all know.
