Just a couple of things I have noticed while pottering around yesterday:
1.  It's very smokey out of the exhaust when you stick your foot on it
and
2.  When driving carefully (remember how this is done....?) there is a point in the power delivery between maintaining speed and just backing off a small amount so the car slows a little (hard to describe) when as the power backs off it's quite juddery until the car slows to match the power being input and speed is maintained again.

Neither of these affect the performance and I was glad I went on a rally driving course a few years ago because the roads were wet yesterday and I lost count of the number of times the back end stepped out  ;D
WRT smoke - what fuel are you using?  I find the more tanks of Asda etc fuel that goes in mine, the more smoky it gradually becomes.  I then whack in a couple of tanks of Shell/BP etc, and its fine again for a while.

Also worth renewing fuel filter, and sticking a can of Diesel Magic neat into new fuel filter and running (it will run like a tractor for first few seconds) - ignore the Diesel Magic instructions about shoving in tank ;)

WRT smoke???  :-?  

I usually fill up at Sainsbury's but I'm going to stick some of the Shell V-Power or BP Ultimate in it when I fill up tomorrow and see if that does anything to help the situation,  I'll also pick up a fuel filter and a can of system cleaner.

it will smoke when first chipped then it will gradually ease off and only smoke on high revs or crap fuel, the juddery thing is the same as mine its done it since ive had the car its only on a manual you get it think its where the throttle position is just open sending  a trickle of fuel in enough to upset the tickover amount which it would be if the throttle was fully closed,
that make sense to you?? :y

Certainly does.  

I had my garage put a fuel filter in today, only took 10 minutes and then took 2 mechanics 45 minutes to get the car going again.  Fixed it by opening the bleed screw on the filter housing, sticking the airline in the fuel filler pipe, packing it with rags and forcing fuel through to the front end.  Glad I didn't try to do it at home..........   ::)

if thatsn the case i would suggest checking the pump in the tank as they bleed themselves within 30secs after a filter change normally!!!
if not thsat you have a drain back problem or air in it!!!! :y

I'm back, did anyone miss me......?   :-?

Just had a few days down inthe Isle of Wight, and bery nice it was too.  Not been before but I'll definately be going back, hopefully in the not too distant future  8-)

Anyway, enough of the holiday reviews, still basking in the glory of the increased power since the chip went in but where is this fuel economy everyone was talking about?  Drove from here down to my Brother's in Hertfordshire, A1(M), M18, straight down the M1, turn left on the M25.  164 miles and 159 of them on motorway at a steady 80ish and get 37mpg.  Not a lot different from what I was getting before  :-?

Thats odd, I jumped from mid 30s to low 40s in my auto the second the chip went it. Must higher on motorway runs....

not a lot but better? dont forget your probably still in the "ooh i can accelerate faster now style of driving" and if the economy is still the same as was when your driving it harder then thats not bad at all, however when you get used to it i.e. on the same runs you used to do for instance the daiy grind back and forward to work you will notice its not using as much fuel as you used to, take it the car is well serviced air filter and things changed etc?
