Spoke to Dan from Redline EFI today
He said not to bother with Power FC and look at getting a NisTune.
Aprox $1100
includes ecu, install, tune.
For a R33 i will need a Z32 ECU or AFM
or Haltech ECU for $1795
not including fitting and tuning.
he gave me a estimated price on it being fitted and installed and said $880 to be safe.
He didn't say the Nistune was bad compared to haltech but they had their pro's and cons.
