Happened again, new loom, cleaned sensors.

OK then no power, 1 second later power 1 second later now power, did this 3 or 4 times until I worked out it would not stop doing it.

less revs OK

Was OK later.

Very odd.
 
Still messing with full tank, but also varies what it does. Will finish a few other jobs first.
 
Still playing up wastegate modulator is on list to replace.

But had the issue today below 4000rpm for the first time.

All intake sensors cleaned, wastegate arm is free. New fuel filter.

I have a brand new modulator for sale £15 +postage if your interested:)
 
OK here goes, wastegate appears to be not sticking, new boost modulator, half tank.

Still does it a bit, but then I thrashed it up and down the bypass and it played up 4 or 5 times over 4000rpm then after a couple of runs started to behave.

Very odd.
 
Just did my modulator and found that 2 of the 3 vacuum pipes that go to it were split/holed.

Replaced pipes, but bore of new pies are bit bigger than original, so still a bit of a problem there. Will source correct bore pipe and presume problem will entirely disappear then, as it did for about 20 minutes when I bodged the original pipes with tape to get me to the shops.

thanks I will check pipes
 
OK found the issue

Grossly overfueling at full RPM

Cost me £225 to fix, slightly quicker full throttle and better on part throttle

MUCH smoother

Thanks Mike
 
So why was that? Map error or duff memory location? If it was an error in the map, had it been remapped before?
