compressor surge should not be happening while accelerating. it will happen if you don't have a large enough bov to support the volume of air going thru when you let off the throttle. even then, you don't "fee" it, just hear a really awesome air getting chopped up sound. lol

I LOVE COMPRESSOR SURGE!

either way, you may have a boost controller/ wastegate issue

ok so if i accelerate i would not feel or hear compressor surge...ie i am hitting the surge line on the compressor map.
