which intake manifold do i need in my life?

[Fredoops]

already have injen intake, plm headers, fujitsubo headers

have an rrc sitting here with a j35

i want more power, better economy, but i do not want to spend money on a flashpro or any other ecu due to the fact it is a daily not a racecar (i sold the flashpro i had)

what are some peoples opinions as to which mani is the best for stock ecu and my mods?

Not with stock tune you wont.

No for both if you don't do some kind of tune, intake manifold makes significant changed to your WOT AFR.

Basic manifold design principles dictates that fat and shorter manifold gives better top end breathing but you lose velocity.... meaning daily driving would be crap, especially low load situations (which relies heavily on intake velocity to push the car along)

Just for the record, there's a reason tuners put the RBC 50/45 degree VTC in K24's when they put in an RBC intake manifold. It's NOT there to add peak power (because you taper down the VTC after VTEC anyway). The higher degree VTC is there to COMPENSATE the power and torque mid-range because of the lack of intake velocity from those short and fat runner'd intake manifolds
