How's it going everyone,upgraded my agu mk 4 from ko3 to ko3s today not remapped yet so taking it ham n cheesy,I've been getting a bit of flutter when I lift off and I'm a little worried I might damage my turbo,I'm still on standard dv.just wondering has anyone any experience with this after the upgrade? Just to mention my DV was working fine before the swap.
Any info would be greatly appreciated,thanks
