Punctuation would be nice also gives us a headache to try reading that and make sense of it.

not sure of your question either.. but a quick google shows 8-10psi is common on a stock L..
depends on exhaust and such tho..

Sorry was in a hurry. Tuck has a 4# lower pulley I figured out by measuring. Explains why it runs on 12 psi. Now I just half to figure out how it is tuned it didn't come with programer so im a bit worried. Thanks for the help tho.
