talk to stece at spohn performance he can let you know. i would say 30's but i would look into to if first.

 

anyone else?

 

Go with thirties at least, I have the 24 svo's on my car and it starves for fuel. With a blower you should really have 30's and i would run the fmu unless you are doing your own computer programing.

with the 6-7psi boost 30# would be good.
but with no FMu id maybe look to 36-38# the
tuner will thank you for the pulse width...
plus on wot passes less likely on locking
the injector up. less duty cycles keeps an
injector happy. and you not going to split the
bank over 24#. maybe $60-80 more.
