find a tuner you like and get friendly with them, then buy a standalone that they recomend.
a power fc is a bit of a pain, it doesnt have closed loop knock control, there is few and fewer tuners willing to tune them these days, and finding a good tuner is a pain, they only have an extra 16 tuning points over the emanage ultimate, and have less features than an ultimate, and the technology in them is old.
there ok ecu's but there is better out there, there on par with a greddy emanage ultimate, but a lot worse than other standalone ecu.
edit: didnt realise u were in ireland, decnt trustworthy tuners are hard to find in the uk.
