What is your boost set to? set it about .8ish...

But yes if your hittin around 5k revs then it will be fuel cut...

My cars doing similar things but I only have a cat back exhaust and the bypassed the boost selonoid.it's boosting at about 0.7 and mine starts at about 4k revs aswell.when I put my boost selonid back to normal it doesn't do it as bad tho.my dizzy cap and rotar arm are good so it's most probably ht leads or spark plugs.

Sounds like fuel cut to me too. Is the boost stable at .8 , or is it spiking? Wastegates on the standard ct9 are quite small, and don't expell enough exhaust gasses when you start playing with the breathing.

Mine misfires even on low boost mate but not as bad so I don't think it's boost spike.also sounds like the cars only running on 3 cylinders when it starts missing

mate u fuel cutin like the tinest bit it can do it said if u plant it in low bost and it doesnt do it thats the prob sometimes the ecu gets use to it and stop after a while i know a couple that has done it i stuck a mani and frount mout and it never done it again as they tend to drop a slight bit of boost but that was my old glanza amd its never hadeney probs after

So the car can boost spike even at 0.6 Iv got a boost gauge and it doesn't get any higher than 0.6 boost but still it feels like misfiring.doesn't do it if i leave my foot half way down on throttle even at higher revs but as soon as I put the accelerator all the way down it starts juddering

thanks mate.I just thought boost spike was when your cars over boosting my boost gauge doesn't go past 0.6 but it still missfires.even at low revs you can here and feel it miss
