how far into boost does it start doing it? it's unlikely to be fuelcut. Fuelcut has a similar feeling to slamming the brakes on. could be missfiring, caused by plugs, leads, distributor or rotor arm
Yep, check the plugs, rotor arm and leads. Mine did the exact same thing, shuddered when it came onto boost and made a low rumble sound. My first thoughts were the turbo was knackered. Checked the plugs and that solved it.
