Well as the title states.. I have a bit of turbo flutter on my ZFR only at light throttle for the most part.. WoT it's just fine and kicks ass. Not sure if I should upgrade to a Forge BpV or if it's in the tune that's causing this or if it's normal for a larger turbo to do this at part throttle. I had a friend install a ZFR recently as well and I heard it was doing the same thing even after he upgraded his BpV, although it was a turbosmart one which I've never heard of so Idk about the quality of that item... he seized his engine though ignored an oil line that wasn't tight enough and kept driving/flogging/logging lol But at any rate, you get the point.

Also, the gear/tire calculation tab.. will this EVER become available to us LNF guys? I'm probably switching to a different tire size this spring in an attempt to gain some traction both on the road and the track. It'd be nice to have my speedo reading correctly, and Hp as well for that matter.

Thanks!
