Cutting Out At High Revs

[KK's-R33]

My r33 has been sitting around for about 4 months. I just got it registered and removed the boost controller. The car was cutting out at high revs because i removed the boost controller. I replaced that hose and it was ok.

Yesterday i filt the car was holding back. So i reved it out in first gear and at about 5000rpm it started cutting out.

Just wanted to know what could be causing this and if some has had this problem how did you resolve it.

Any help would be great.

Cheers
