My VIII's original owner put a EBC in it before he was forced to sell it. It was taken out, and I learned the hard way that it wasn't done properly. The vacuum tube with the pills for the wastegate solenoid had been ditched and was replaced. Are there any other bits that could be left over that need to be fixed?

I've been trying to figure out why my WOT seems numb, with a Dynoflash mail in as its only decent mod. I've chased out a couple leaks (TB shaft seals and stock DV) and it seems to boost ok. I've been told that the basic Dynoflash mail in can leave something to be desired.
