well i was kinda dissapointed with only 21 hp gain, i was lookin for 23, but i think i got a bad batch.

Double up on them. I run 10 wires on my B series plus the Ebay ground system. 340 to the wheels off the bottle.

i was thinking about that, but i didnt want to overload my header manifold with all that spark, but i was thning of getting half blue, and half yellow = 32 TO THE WHEELS.
