Put in a cheapie manual boost controller (needle valve) and see if you can get it under controll. If I remember right it only costs about $10.00. The problem might be the wastegate..If it is having trouble flowing much more than 10-12 psi then it will have a much greater tendency to spike, especially with your mods. If the valve dosent work you might want to port the WG...may sound extreme but it will not hurt.
