im not too sure on what timing its running as i bought the car with a re map on it, iv only got reciepts. it peaks to about 20psi and drops to about 13psi ,, where i live we can only get the 97 fuel unless i travel a bit. all the back pipes should be good as i re did them all when i removed the n75 valve and the secondary air pump
iv said a post on here before about it holds back for a second before boost and i still havnt sorted it so do you recon it could be related? i need to buy an air flow meter really
cheers

only thing it ever comes up with is secoudary air pump fault as i have removed it and put a resider in place the fault comes up now and then when i let it idle from cold.
i have been using a snap on verus scanner but it never seems to find any faults apart from the one i said.i bought a cheapy cable of ebay vagcom but i aint got it to work yet.
misses under load for a 2nd when u put ur foot down.

Logs should ideally be captured in 4th gear to get a good dataset.
Those MAF figures are very low but we need to see more logs before being able to diagnose further.
Try getting blocks 002, 020, 115 and 118 in 4th gear runs within quick succession of each other

I've done some logging today but i don't know how to post my results, i tried to post it through a link on photobucket and i need to have 15+ posts to do it. Can i post it through a link to the actual excel file?
Another thing; Whilst i've been trying to do the logs my cars been getting worse, misfiring and going totally flat but not all the time. Also a couple of faults came up up, one was misfire on cylinder 4 and another was multiple cylinder misfire. I'm guessing it's the coils but would anyone recommend the bolt down ones for S3's that you can buy off ebay as i'm currently using the bolt down ones?
Cheers
