I want to avoid an external setup if I can. I made a 1/2 inch hole between the scroll ports, and bored the wastegate hole a little bigger....No difference. So, I will try and bore it more, but I really just dont think the hole can be made big enough. I also have a bit higher compression, 9:1, so maybe thats contributing to that. Seems to climb to about 14 or 15psi now and stop. I guess thats an improvement. Thanks for the input guys, Im going to bore that hole a bit bigger if I can and see what that does.
