hyperdrive seem to be the place most ppl get a nistune installed, but quite a few other shops do em.
yeh its $880 or so for install + tune
but i got mine for $650 as i already had a chipped ecu
i was speaking to andrew (owner) about other ecu options such as power fc and greddy e-manage, and he said sumthing along the lines of
"if u want a hand controller, go the power fc..but its no better than a nistune. dont go a emanage..even though i am a greddy distributor i dont like to promote them. nistunes are awesome and do the job extremely well"
