every time i try to bring the buick up on boost the car just seems to roll...i installed the bigger/softer rear shoes,aluminum drums,s10 cylinders,also put in a linelock to help keep the rears from heating up during the burnout...the only thing i have not touched is the front breaks or the vacuum brake setup....i have a good pedal and good stopping power...do you think my problem may be my front pads and rotors being shot??if so does anyone have a good upgrade without breaking the bank,i don't really care about the bling i just want to be able to build some boost at the line....my best 60' so far with like a 2psi launch was a 1.57...any help would be appreciated...thanks
