Ok, so I've now done 500 or so miles since converting to manual....
All in all, bedded in very well. Am used to clutch uptake and gear change - all good there.
The remaining niggles:
1) Need T2 to configure it as a manual, and remove TC light.
2) Sometimes if given a rev from idle, it will hold the revs at 1.5k for some time, before suddenly dropping to normal, after over revving for a minute or so. Have removed inlet, replaced all LPG plumbing, checked all vacc pipes, all good. Need to see MAF readings at idle to go further, and my KIT is fubar. No codes. This problem is worse on LPG (but aren't all problems)
3) got an annoying squeek from gearstick!
4) Seems to be a few flat spots when booting in second. But still stupldly powerful. Wonder if this is because ECU needs telling it's not an auto anymore.
5) The mid range good condition tyres I have on the back, are no good for a 3.2 manual. Premuim tyres ONLY on this combo.
6) If I was being REALLY picky, probably a small amount of play in the drivetrain
7) The box does like to whine in the lower gears. Even SWMBO is making sarcastic digs about hearing the gearbox over the radio! Maybe if I get a really nice day and am at a loose end (yeah right!) I'll pop the other manual box on there I have in the shed!
That's about it!
Other than, I STILL need a gaitor, and original gear knob, to replace the, er, "alternative" silver one!
Do I regret it? Not at all! As before it's soooo much more usable than an auto.
I overtook a car on an A road the other day, and the plank gave it all he had in his Golf to try and stop me getting past.

The ten year old 3.2 ate it for breakfast

(making him look a little silly in front of his Barbie!)
