If you are going to program your truck down the road (ostritch/auto prom ect) there's excellent settings in there to controll boost.
If your not going to do that You can use a boost controller from
www.rjcracing.com
It keeps the wastegate closed till the desired boost and then opens it and holds steady. There's little to go wrong with it and is very reliable. And inexpensive. Don't buy some E-bay cheap junker. They are not the same.
I use the RJC on all my GN powered vehicles and our Typhoon with great success.

Keep in mind that the stock chip will boost cut at 15psi~!
