The Power FC will do everything you want for a street car.
You Don't need:
1. Anti-lag
2. Rotational idle
The only disadvantage of the power fc is that you must run an afm of some description (nissan Z32 is the most reliable to use).
The power fc retains all of the oem
ecu functions (a/c idle up, thermo fan control, O2 feedback, utilizes factory boost control system etc) without requiring additional license costs.
There are no hard-set limits in terms of power, kilowatts, horsepower or turbo size etc its purely as good as your tuner. So if you have a good tuner then there is no logical/physical boundary etc.
The Apexi 1200HP drag car uses a PowerFC for its main
ECU (no surprise).
It has plenty of map resolution (20 x 20 = 400 map cells on both Fuel & igntion).
Please read the power Fc faq for all the finer details:

Thanks Ajayjay, but Sean @All Star is the real PowerFC guru.
