Question EGR question??

So I just finsihed with my diamond eye downpipe and I blocked the EGR. The only thing is that I noticed I didn't reach peak boost like before?? (37 psi) it only boosted to 35 psi. and the EGT's seemed to be higher than before! go figure?? Please advise!?

well i assume that the quadzilla did that but i didnt specifically adress that. for now i run banks six-gun with a quadzilla for the dpf delete and assuming the EGR as well. Im going to go with EFI Live in a matter of weeks
