It sounds like the secondary injectors aren't coming online or there's a ground problem...or both.

I'm still in the process of fixing mine..



All of my injectors are fine, I'd say its your ground.

When any of the guys here (Australia) replace the factory

ECU with an aftermarket one, all problems are fixed.



However, its a big price to pay just to eliminate a hesitation.



It's really weird though, it seems the more you drive it, the

smaller the hesitation is..



Where as, after I had flooded my car.. the next 500kms had the

hesitation real bad! But it has gradually improved since then..

Is it like a drop off in power at 3800RPMS? or is it a bump in HP (like it dips for a second then comes back, more of a "hesitation" so to speak)?. If its just a hesitation then you are suffering from the infamous "3800 hesitation" (speaks for itself). You should be able to run a search or so to get lots of information about it. I would say probably an ECU ground, and/or your harness ground. If that doesnt fix it you might have to resolder some parts on the ECU. Good luck.
