Bleed Valve

[M3EVO]

Many moons ago, I owned a Series 1 Escort RS Turbo. It was a standard car apart from a S/S exhaust. To acheive a performance gain I used the bleed valve concept to confuse the ECU into thinking that more boost was required by fitting a valve in the signal line from the inlet manifold to the amal valve (think that is correct). This would then hold the wastegate actuator so more boost was acheived.

My question is - Can this method of tuning a turbocharged car be used on more modern cars such as the VAG range of 1.8T's???

No the question is for a friend of mine who is looking to purchase a Seat Cupra. I drove the S2000 and it didnt really light my fire so to speak so the wife and I are still in limbo about what to do.

Thanks for the reply.
