Assuming you have Boogies and NGK's properly gapped and timing is spot on, check base boost by disconnecting the APC and see if it boosts to mid-yellow. If so, is the missing still there under high loads? If not, could be the aggressive APC you have is causing issues. Also, a clogged fuel filter will cause problems in an otherwise well-running car when it is put under high loads. You can check for intake system leaks by removing the AMM and inserting the pressure side of a shop vac into the open tube and spraying soapy water around all of your connections. Correct any leaks found. Good Luck!
