I have a '91 VR4 w/ APEXi AVC-r (see sig for all mods) and from a cruising speed if I downshift into 3rd and push hard it misses at around 5k. It doesn't do this if I run hard through the gears from a stop. I have done the fuel pump by-pass (thanx everyone for that info) and that seemed to help a little. Any Ideas on how to fix this would be greatly appreciated.

Plugs are 1 month old and the gap is .040. The car has 133K on it but otherwise feels like it's in good shape.

Watch your boost. If its doing it in third and the boost is near 14-15psi, its the plugs

Thanx everyone - it probably is the plugs 'cuz it does start to miss at about 1 bar.
