yes low compression engines allow u to run more boost mate other wise they r pointless.....
dependin on how gd ur management is set u can run alot of boost...
but too much and ul bend a rod...
aslong as manaegement , be it efi or mfi, is et up well id say u cud run between 20 - 25psi!
but dont hold me to that... others with greater knowledge than me may say otherwise!
