is a z4 ecu better than a prodrive 6k chipped ecu?

 

no

 

z4 is a prodrive map. but with 12.73psi 0.9bar
6k is 13.33psi 0.92bar but this ecu is for an sti v2. so may not work on others, where as the z4 will.

 

ive already gt an z4 ecu but im looking at this one which is a 6k chipped ecu wich is meant to be better than my one

 

if its chiped, then may not suit your car mate.
alot of persons have found this.
& if it is chiped, may hit 16.5psi 1.1bar

but the last time i tryed an sti ecu on a wrx/uk it wouldn't work. so check it out first mate

 

ive had both, the 6k is far better than the z4 on performance and the petrol use aswell

 

cheers guys
