Thanks DD great numbers I can quote to tuners/queries regarding fuel supply
Thanks for info Dave. I understand exactly what you are saying, I have played with the jet screw heaps trying to tune it.
General info I have been told is that you shouldn't be able to start the car without the choke on. If you can its set too rich for idle.
What you said re needle is exactly what I was expecting to have to do. The issue I have is the other variables that need to be fixed before you start to custom change the needle profile.
To be honest I think its beyond me. I have found a reputable tuner and have booked it in with him. I will let everyone know the results.
Once its running well I will note all the variables exactly and measure the needle profile with a vernier at the 16 spots so others can have a closer start point than me.
To be honest the entire turbo process has been so much more complex and involved than many people eluded to on the forums when I was first asking years ago.
To anyone considering this IMO if you have gone this far do it properly with EFI
