Hi guys, last week I did maintenance on my mk5, at the end the IP was 9.2, when inhaling it drops to 8.4 and recovers almost immediately, no creeps, solid, but surprise, when I check the IP with 30b it drops to 7.9 b, there is a 1.3b difference from a full tank to an empty tank, which is too much, I dived with it and my 156 and everything was normal, I don't notice a difference. I like to leave the I.P in the low range for these regulators, according to the manual an I.P that is too low with the tank almost empty is a devil spring. Would you put some shims on it or would I leave it as it is? I am almost sure that if I raise those 0.7b at low pressure that I am missing, with 200b I will be over 10b of I.P and I don't like that. I think it can stay that way until I get a new spring and try. What do you think? Greetings
