wrong,

ECUTek / ECU based boost control in my experience from the user stand point has always been superior to a third party / separate control unit. as long as your tuner knows what he is doing the ECUTEK boost control function will be superior than the HKS unit.

So would you install the HKS anyways or completely negate it?

My tuner is Sebastian at SpecialtyZ an he said by using EcuTek he could dial the car and the boost in better. But he is a guru with EcuTek your tuner may not be a comfortable and knowledgeable as Seb is with EcuTek.

Would you have Sebastians contact info...I am thinking about sending him my dyno charts and ECUTek tunes to see if he recommends anything else

To Chuck's point, I also had read of this (see below). The opinion is that the frequency signal from the solenoid valve apparently isn't as strong as it could be to accurately produce a reasonable wastegate reaction time so it would be delayed compared to an EBC.

Until this, Tony said they have been using 4 maps as hjo1078 says below. 91 or 93 map, E10-E30, E30-E50, and E50+ so to a point you still have to monitor what tune you are running based on fuel in the tank. Now, it sounds like this won't be necessary with the new software that ECUTek has. You could still do the 4 maps if you wanted so you're not always running high boost I suppose.

Just the messenger here and know enough to be dangerous on this so don't shoot me! :roflpuke2: Hopefully we can get further info on this.

it is all dependent on what solenoid you use to control the boost. most manufactures use the MAC solenoid, which is highly popular and inexpensive. that solenoid tends to work best between 31-33Hz

however there are other solenoids that are designed to work in the lower Hz like this unit

Humphrey Online Catalog 1533712VDC | CDS

like i said all dependent on user level and experience. MAC solenoids are easy to find and popular so i don't blame if it's easier to control with conventional controller *shrugs* factory GTR solenoids and GM solenoids work in the 20Hz range yet 50psi on those is no problem; see where I'm going with this? half the battle is proper plumbing, the other half is proper hardware. then the ECU just brings it together.

if I was tuning the car myself i would be using the ECUTek boost control function. I would highly recommend you have the tuner tell you what to do as their experience and comfort will highly depend on what they will want you to use. send sebastian@specialtyz.com an email he is the best e-tuner i know.
