I put a -31 on it and a chip and it was peaking at 1.2 bar with 1/2 a hole pre-load. I didn't test it properly because saw 1.2 bar and backed off before seeing if it settled

I removed the -31 before I caused any damage but when I put it back to standard I noticed that the standard one is spiking like this and it got me wondering

I might put the -31 back on tomorrow and give it all another go
