If In doubt, Flat out!
Hi guys, I fitted a new stage 2 hybrid turbo, along with a V3 Manifold, and ever since, I have had a turbo 'flutter' on WOT. I am running Revo stage 1, which was fine before the work took place (with a stage 1 hybrid before). The car drives better than ever, other than this flutter. It pulls nicely on part throttle. I have done some research and come up with the suggestion of 'boost surge'. What I am asking is what would cause this? The DV was fine before, but could the turbo be producing a bit more boost, making the DV bounce? The main suggestion I have seen is to get the boost turned down. But this seems a little extreme to me, as it was running fine. Could it be due to set up on the actuator? (I am not great with turbo's, so sorry if this was a silly suggestion). Also, N75 valve... could this have just given up? I have also deleted the SAI, but can't see this being related. Hope someone can help. Thanks
