New wg and cant controll the boost. HELP!

[HiImBrian]

So it's 3:00AM and I just finished putting on my ported 2g mani and 40mm HKS wg. Before I had this external wg I was running 10psi w/ a stock internal wg. I've got a stewart warner boost gauge so that's accurate. And my boost controller is a Joe P. After I put on the new mani and wg my boost just shoots up to 15+. I let off as soon as I see it over 10psi. I addjusted my boost controlled all the way down and all the way up and my boost still shoots way past my safe and happy 10psi. Why is this happening?!
