Ok I had a 10 plate in my truck took it out and put a 0 plate in. with the 10 plate I was boosting around 40 psi. now with the 0 plate Iam boosting around 33 psi. It felt like the 10 plate had more power than the 0. I do have the wastegate pluged off. any ideas

 

gotta boost leak somewhere?

 

I have the hose coming off of the wastegate pluged off.

 

ok, check for a cut in the line or maybe in an intercooler boot, when i had the wastegate plugged i could hit 45psi no prob... every turbos different tho
