that 6al/blaster combo should have no issues with that setup. Id start looking elsewhere, wiring, plugs, wires, cap,rotor. Does it have a crank trigger ? if so gap on that.
If you still have the pro coil from your car try that also, coils do go bad sometimes.

thanks for your input guys, I did start the car in the dark but didnt see no arcing anywhere. put my 7al 2 plus box in thursday morning no where to check it out.so i left for joliet ill. first pass 10.11 poping and missing, went back to the pits and put my power pro coil on. next pass 6.05 in the 1/8 114 mph 9.50 in1/4 @142 mph. nice to be back to normal. i'll be back to 131 motorsports park now. it was frustrating there for a while. thanks again for your help, ray geeting@sky high racing.
