Well it all depends on you and what kind of fuel managment you have. The higher the compression the faster spool with a turbo which equal less lag. However on that note, the higher the compression the easier it is to blow **** up if you dont have proper fuel management and timing. I personally like high compression and lower boost amts. Most people play it safe with something like a 9 to 1 compression on most forced induction cars. If you are planning to run around 7-10psi then i would say go with 10 to 1 compression.
