Stock 2.7 S4 boost

[sitas3]

Hi, anyone know what boost a stock S4 should be pushing out? Mine is just short of 0.8 bar max..

Yep, sounds about right.

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]
