Don't remember exactly but i think that i could barely get to Zero Boost when foot braking the car
it would be pushing at 1200-1300
i had a D-7
YOU WILL HATE IT well i did
i couldn't even do a burn-out and the boost wouldn't come in til about 25-30 MPH
the only good things about a stock D-7
1-it was great on gas
2-the tires would last for ever
3-you would never loose traction OFF the line.
4-You would never over boost or boost at all in first gear.
