S62 diaphragm springs slow down response

Is there any posts about S62 diaphragms? Haven't found any info about increasing response.

Hi!!

I have news and I wanted to comment it here with you (in case it happens to anyone else). As I mentioned, I have changed millions of things out of desperation and without knowing where the error could be.

Before Ichanged the head gasket I didn´t have any problem, therefore I focused only on the things I had touched.

Error 1: Doing the vanos test with the Launch X431Pro, it always gave me vanos failures. As soon as I did it with DIS, it confirmed that the vanos worked perfectly (it was too late...it was all new...).

Error 2: The car kept failing and I started thinking: what if, with the fuel line disconnected, the fuel filter has dried out and now it doesn't let enough pressure through? This weekend I changed the filter (it wasn't more than 1 year old) and exactly! It was hard to blow through it! The car now burns without problems. I need to finish it and do longer laps, but I THINK the problem was there!!

Thanks to everyone for the tips!!

Regards!!
