You can see the stock (most all bolt on's) motor was quicker, somthing is definenintly wrong, I'm almost sure it's ingnition related but I can't find any bad connections or lose wires.
Timing is at 15 degrees, with 93 octane and aluminum heads should I bump it up a little??

Could it be the used A9L cpu, or would it act up worse?
24# squirters are used too but they were clean and don't tick.
