hry guys i have just recently sold my toyota supra and my r32 gtst and gone to a r32 gts4 but i have seemed to noticed that up top end round 4500-5000 maybe higher there is a poping sound like a miss my mate has the same prob with his gtst ? could it be spark plugs? or coil packs, too much boost mine is only on stock but after booting it i can smell a really strong fuel smell as if my car is running rich i only run it on bp ulitmate and there is no smoke coming out my exhaustat all even in between gear changes its all sweet any ideas would be great cheers matt

You're hitting your rev limiter lol.

And yes, you're in the wrong spot, but check your coil packs.
