Hi all
Having fitted my new head the boost pressure has dropped and now I am thinking of upping the boost more by switching to a 17% pulley.
Just to get a collective answer does anyone see any disadvantages from switching to a 17% pulley? (or advantages apart from more power

)
I initially went for the 15% as this is at the top end of the operating scale for the s/c before excessive heat is produced and it seemed the safer option as I had stock I/C.
