cheers. my boost curve for comparison. looks like the boost lasts longer than my old S3 [img]images/graemlins/smile.gif[/img] seems to flutter a bit at max boost though.

Looks quite good imon, I assume you plotted this with VAG COM, can you give me talk through instructions on how to do this as I am a VAG COM novice (amongst other things, before anyone else makes comment)

That's perfectly correct for a stock S4. That 'flutter' is normal too because the control process is of the simplest kind (open wastegate, close wastegate, open wastegate etc.)

BTW - there is something wrong with your S4 - it is in need of a remap [img]images/graemlins/grin.gif[/img]
