Hey, did you get a comparison dyno run in the end?
Not a successful run in the end. I managed to adjust the wrong way and ended up totally opening the valve. Have since done it properly and just by feel can tell it is improved. Can also now hear some of the supercharger whine Seeing as I got the dyno record for that dyno, not sure how accurate that 537 as a true value was tbh, just wanted comparisons really. Plus, by that point the car had been on the dyno for quite a while due to operator error so was probably fairly heat soaked. But yeah, the way I adjusted it opened the valve completely.

Cool, so there might be me with a 10mm spanner tampering in the engine bay BartW said:
Ok, so we did it on both cars. On the white one it goes up to 60kpa and on mine goes up to 58kpa? This is me looking at the lower right hand side gauge on the centre console. It also felt slower than usual.
When modified correctly, should see about 65+kpa on the EDI. Can you make the Ely meet next week? Can check it for you if you want R8VXF said:

I don't have a pressure gauge on EDI, or do I?
Ely meet, where / when is it?
It is the one you are looking at. Ely meet, where / when is it?
Ely meet is a week on Saturday, thread is somewhere in HSV&M, will post in it to bring it to the top
