got a 93 si lude with all the airways opened up a little larger, stock fuel set-up and advanced ign timing with msd 6a ignition and blaster coil. after the car warms up and i really go to take off the car kinda bogs down or misfires. it only does it once the car is warm and does it almost all the time now at wot. anyone have any suggestions? i dont wanna take it to a dealer cuz i know what they will say (it must be all these aftermarket parts). so if anyone has any suggestions please lemme know

If your ignition timing is too advanced and your knock sensor senses knock or ping or detnation, then it will retard the timing until it doesn't sense it anymore. Have you replaced the plugs lately? Are they platinum? How about plug wires when did you replace those? Dist cap and rotor? Did you do a timing belt recently? Run some Chevron with Techron through to clean your injectors. Have you changed the fuel filter lately? Start with the free checks, then the cheap ones. I have the same prob and don't know what it is yet.
