I have a deltagate wastegate, and I took it all apart and cleaned it out last night but Ive read that a lot of people have problems with boost spikes when useing it. I was wondering, if the turbo is internally wastegated, if I make my manifold to support an external wastegate like the Deltagate, could I use both? I thinking is that if the external WG spikes, the internal one on the turbo should vent that spike assuming both are set to the same PSI.

Is this logical or have other people done this?
Thanks.
