Hesitation for a split second at 6000RPM in 3rd gear??

Hey guys,
Anyone ever have a hesitation only for a split second right at around 6000rpm. It only happens in 3rd gear and does not happen everytime. The car accelerates hard then falls on its face for a split second right at 6000rpm and then accelerates hard again to redline.

The only mod so far is a profec b Spec 2 boost controller (installed it in preperation for the DP and Cat back that I have waiting to be installed)

Peak boost never gets over 10.8psi.

Anyone ever experience this?

Thanks, Jason

Hmm I just found this...

Here's the fuel cut chart:
1000rpm-11.8
1500rpm-11.8
2000rpm-11.8
2500rpm-11.8
3000rpm-12.2
3500rpm-12.4
4000rpm-12.8
4500rpm-13.3
5000rpm-12.2
5500rpm-11.3
6000rpm-11.1
6500rpm-10.7
7000rpm 10.7

I wonder if I hit fuel cut. I will lower the boost to an even 10psi and see if that cures it. :icon_tup:
