Msd digital 6 question

I have a digital 6 6531 ignition box with a 67mm turbo.

When i hit the 2-step and floor it, the car holds at about 3000rpm and builds bout 3-4 psi tops and when i let off it the BOV snaps, so i know im making boost.


SHOULD i be making more boost????

thanks

my wg spring is set at 9, and i see 9-10 when i stab it.

If I am correct on this which I may not be. You may have to set the 2 step higher to build more boost. I'm sure someone will jump in here and correct me but thats fine.

I dont think so....there's not much load in neutral and at that low rpm...the more load an engine has on it the better the boost will build...someone correct me if im wrong

When there is no load on the car as in a 5sp car you also won't to pull some timing away when you are on the two step for a little more boost, the digital 6 has that option which makes it nice.

set the 2 step higher and pull timing.

when you put my car on the 2 set it was set at 3800 and pulling some timing.

gonna be harder for your motor to make boost sitting still then mine... WAY more motor lol

Late burning fuel will spin it up some more. Plus you got to love the bat mobile flames out the exhaust.

How have you smoked the centerforce on street tires? I'm still running the stock clutch with M/T drag radials. I have made about a dozen passes.
