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?
