Hi I have a 2012 Camaro ss just recently went and put in a btr stage 4 cam. after getting it tuned one day I cam out started it and noticed there was no oil pressure but after 10 seconds or so jumped up to 30+ psi and remained normal the entire drive I already replaced oil sending unit so I’m not sure exactly what the problem is… I really hope y’all know what’s going on thank you

 

Probably just a little air in the line,if you're not getting a nasty lifter rattling noise I wouldn't be too concerned.
