Perhaps you did not read my post, in which case I will break this down for you.

The turbo itself does nothing but blow hot air. It has nothing to do with boost control. That is what the wastegate is there for, if there was not a wastegate the turbo would just compress to its limit. The wastegate opens at a certain point to allow those exhaust gasses to bypass the turbo.

Even if he was running an evo3 16g he would still be using the deltagate wastegate not the stock wastegate. That is the point I was getting at. No matter what turbo he was running it would still come down to the wastegate.

Please someone, if I am wrong chime in.
