Im a noob with turbos since this will be my first go at one. I am running a b18b in a 92 dx hatch with dsm blue injectors and a pretuned ecu from pharable.net.... do i need to run a resistor box for these? Also I was wondering if there was any way to test a internal wastegate... i dont want my first pull to be a spike that will blow my motor.. thanks!!

 

yeah thats what i was thinking.. thanks for the help man

 

You could also uses a hand vacuum pump like us cheap guys...use a vacuum tee on the line and an air gun into the vacuum tee. Most vacuum pumps read positve as well as negative...
