yeah they are a easy mod, depends what you are running now
Boost Targets & Fuel-Cut Limits
WRX/STi Saloon ECU's 2C, U8, W6, W9 - As above, 11.47psi held to redline. Fuel-cut 14.57psi
WRX (1995/96) ECU Z4 - 12.71psi, dropping to 11.78psi @ 6600rpm. Fuel-cut 15.65psi.
UK/Aus/Euro ECU's V7, 7D and 6D - 11.47psi, dropping to 9.47psi at 6600rpm. With Fuel-cut @ 14.87psi
UK Prodive ECU - 13.33psi (peaks to 13.64 @ 5600rpm, drops to 12.71psi @ 6600rpm). Fuel-Cut 15.65psi.
STi RA (1996) ECU 7K - 13.17psi (peaks to 13.64psi @ 5800rpm). Fuel-Cut 15.96psi.
WRX Wagon ECU V9 - 10.55psi dropping to 6.84psi (starts to drop @ 5000rpm). Fuel-Cut 13.79psi
But then this from Scott.T blows a hole in things:

Just compared the 6K (after finally getting hold of a base map, thanks Andy). And can confirm it is the same as a UK PPP map.
I thought the Z4 base was v.close to the PPP, but the 6K from the STi 2 is nigh on an exact match.
that'll shock a few people, knowing that a UK is running an STi 2 map LOL !!!!!!!
Bit strange though how Prodrive rated the PPP at 250BHP and the STi 2 is supposed to be 275BHP. Must be down to mechanics rather then electrickary 1's and 0's.......

i have a 6k ecu that i fitted to my 93wrx it ran alright BUT i used to get the MAP come up as an error yet i know some people have fitted them and they were fine.
You're more than welcome to have it if you like (for nothing) as i can't use it as i've changed my impreza for a later model
