My overkill PCM did that for the first few starts. Thought something was wrong. Left the battery unhooked for 30mins or so, and left the key on (to drain any residual power) Hooked it back up and same thing. After a good "spirited" drive (10-15 minutes) it never had that hard starting again. It actually started much faster than normal (though Will states he has his PCMs setup for his 'quick start')
