So does it lower drive pressure (Helps fight drive pressure issues)
no it can actually create higher drive pressures if the turbine is too small and on paper the cam looks like it hurts the boost drive ratio once the turbine gets overloaded compared to a stock cam.
For example with a 38r.... the drive pressure starts getting out of ratio sooner than stock heads and cam because you are moving more air through the engine at a lower boost level, but the turbine is seeing increased flow. You will reach the turbine's flow limit sooner but also spool up sooner. The thing I recommend is drilling the divider through the wastegate hole and letting it (the wastegate) force itself open at about 34lbs of boost or so. This way you get the instant spoolup, but the drive pressure starts getting dumped when the turbine gets overloaded.
Since the cam has less overlap than stock, you don't have to worry about egr (cute name but exhaust is literally trying to force it's way through the motor backwards) happening when the drive pressure exceeds boost by a large number. That's why most cams have made less power on these motors. You don't want EGR at WOT.
