Hi there guys, very stressful week for me as I'm not sure now what to change next, let's start this from the beginning, driving normally is fine with boost everything seems OK, I put my foot down half way and lovely boost kicks in as it should but when I go to full throttle it, boost happens for a bit until boost cut, but then no boost at all, then I fever the halfway mark on the accelerator then full boost is back then full throttle again and no boost at all for 2minz no codes come up on it no eml nothing, start the car warm it up and then go, boost is all there again until full throttle, can anyone please help me ( I've changed the following), dv valve, n75 valve, sparks plugs coil packs & fuel filter (doesn't miss fire) plllleeeeeeeeaaaaassssseeee heeeeelllllppppp meeeeeeeeeeeeeeeeeeeeee
