Getting of the line was my problem, since I am in a wheelchair and use handcontrols to drive, it is hard to build boost at the line. I was leaving @ maybe 4 or 5 psi. The hancontrol is pulled down and toward your lap for the throttle, and for the brake you push forward toward the dash. When I power brake to build boost the throttle pulls the brake away from the dash. I think I need a line lock to hold the brake while I build boost.
