1 Bar Boost Spring 930?

I posted this topic in the 911 forum so I apologize for the re-post. I am looking for some information on adding more boost to my '89 930. I was told by my mechanic that the 1 Bar boost spring is the way to go. After consulting the 911 forum there seems to be some opinion that the 1 bar could cause the car to ping and I should go with a .9. Any ideas or information would be great. I was also wondering if there is an actual Porsche part that the dealer offers to do this and if so what the part# was. I also live in Denver so I am a mile above sea level. Thanks for the help.
