Not to say it might not be an issue with the chip, but have you checked for any engine codes that would indicate some other problem (vacuum leak, coil going bad, plugs that need to be replaced, etc.). The stage 1 chip will run the car at a richer a/f, which might just have been rich enough to foul out a plug or two if you already had a lot of miles on the plugs to begin with.
Good luck getting your car back on track!

p.s. have you checked to make sure all of the connectors going into the ECU are pushed back in tight?
