Hang on - where does it say I called you or anyone else on here a chav? Maybe you just need specs to fix your MPG problem??

Aaaanyway... An interesting point, and a recurring theme on SCN, is that 28mpg or 35+mpg on a long-run suggests the latter figure is a barometer that all's well with an LCR's running efficiency, while the former indicates a fault.
FWIW, my LCR (OE map) used to do 35+mpg on a long-run, now averages 28 - still trying to discover why...

Well based on what I discovered at the weekend I'd suggest checking for PCV leaks, that was what did it for me.
Oh I don't think there's anything wrong with my eyesight, I can spot a troll a mile off.
Would a PCV leak have shown up via a smoke test? (Had a smoke test, garage reported: "No leaks.")

Depends on where the smoke was injected, I've never had one done so not sure. I'd have thought the PCV and boost systems were separate (apart from the PCV vent going back into the TIP) so maybe not, but I'm not an expert.
I'm a troll for speaking the truth about quoted RR figures? Good luck with the MPG fix, took me months to find my fault.
No you're speaking your opinion and telling me that I'm wrong for believing otherwise, and slagging off my car. Your "point" was off-topic in the first place as the thread was about an MPG issue, not whether or not you think my car actually makes the power stated by the RR. And if you'd actually bothered to check you'd see I've already found and fixed the MPG issue. But hey, don't let facts get in the way of a good trolling session eh.
How am I slagging off your car exactly? My BHP figure was followed by a cartman, hence a joke - followed by advice about MPG's.
As for RR's, I'm open to your beliefs - did your RR operator unbolt your engine and attach a dyno direct to the flywheel?
How did the operator work out the frictional losses of all the cars on the RR?
For your info, a RR should be used as a before and after reading, ie - before and after mods (even then its questionable due to variables and operator etc) - to quote a flywheel figure when nothing even touched your flywheel is just daft. All guesswork and extra income for the operator.
So what, you're saying you do believe the figure then? Get your story straight.
As I said before, the standard cars there that day (including one LCR) made standard figures so I think it's pretty safe to assume that whatever method they use is reasonably accurate.
For your info, I'm well aware of that thanks very much, I know well that flywheel figures on rolling roads are estimates based on wheel torque and coast-down losses etc. You clearly seem to think you know far more than I do on the subject though so I won't waste either of our time arguing with you any further.
Please elaborate - looked in your thread, no mention - re the fault you discovered.

Well It's not a REVO map on mine don't know who's it is because it's "locked" can't get in to read it or even view it ????
which software does that ??

I thought Revo did that, could be wrong though. How did you check? Can you even get a checksum of the firmware image?

MAF. No signs of it been dead. But once replaced MPG shot up.
Also worth checking thermostat and coolant temp sensor. Is your temp gauge on the dash reaching and staying at 90?
Mine was but when i was playing about with the Torque app I noticed that the temp display on there was only getting to about 75 or so. Turned out the thermostat was stuffed. That will affect fuel economy as the ECU changes the mixture to get the car warmed up, if the thermostat is gone then the engine never gets to the right sort of temperature.

Thanks to advice from Lee69 and Andycupra, the 'stat was recently replaced, which has seen an improvement on local B-roads - now up to 28-32mpg - but it's still crap on a long-run.
MAF was recently changed (pukka VAG, supplied by Sere), but made no difference.
Someone also suggested a dodgy N75??
Have booked a smoke-test to suss the PCV...
