I stopped the turbo surge on my TA-49 with the "tornado" It works, no more surge at part throttle.When I upgraded my turbo, I decided on an 4" S ported shroud.....no compressor surge, even with my Precision SLIC.
If you can get your hands on a Tornado, it should reduce or eliminate your problem .
Do a search on this device.
thats not what i would call surge ..surge is when you part throttle boost like to pass a car and reach around 17psi up to 20 psi and the compressor starts surging basically bucking the motor and can be very severe on a ta49 with a maf based ecuMy problem is when I let off the gas while building boost the air back flows and causes the compressor to flutter.

if your encountering surge it sounds like your stock turbo is a ta49 .. the turbo is the cause the big neck SLIC only makes it worse but the maf is what makes it more noticable ..one fix is go maf-less speed density
