ive got a question, a mate just bought a gfb bov, (same one in the vid) his installed it, works perfectly, but doesnt get the whistle when his driving (changing gears). is der a combination on how much atmo and recirc ?? also theirs a engine warning light, after his installed it ?

@184silvia Hey there, I just spoke to him on the phone, and now the spring pre-load is correctly adjusted the check engine light is no longer an issue. The whistling trumpet is not whistling because it's the wrong part # for that car - in the vid we used part # 5702, as opposed to 5701. The only difference is the 5702 whistles more readily, where the 5701 is for higher boost systems.
