90 psi if I remember correct is bottom of the okay range. Obviously the more the merrier but it does depend of engine temp and cranking speed. I believe that's 90 full operating temp 250and rpm

 

thats what i found too. i saw it said like 3 bounces of 85 and then progressive rise was good. or 110 was fantastic. and bounces under 85 and then slow rise is bad. i just found it this morning. google is a better search function. lol on here it gave me compression and something else. didnt work at all. lol oh well. thank you for responding
