Hi,
Wondering if i have a problem or just my mind worrying.
I have KO4's and have recently had it all live mapped.
Now the car peaks boost at 20/21 psi, and drops to about 18psi.
Now in some gears it drops to 16 psi, while higher gears it only drops to say 18psi

Also yesterday i was accelerating hard through all the gears and it felt like i was getting pulsating of boost?!?!?! but was not quick enought to look at road and guage, any ideas???

Thanks
Nick

I had the pulsating boost in my S2. I cleaned the maf and all was fine after that.

Train your eyes to move independantly like American fighter pilots



Have you checked your DV's?
You could try replacing the N75 and checking the pipes that connect to it.

TTB, N75 or dv's .... have you had a health check ..?

Try going to vag also and clear codes.
See if this helps even if you have no codes.
If no leaks do n75. Iv been going through them in 10k miles they go off and boost drops ever so slightly and has a little lump just after peak?
