If you think it's the chip, do you have another ECU to replace ? Was it running all good before the chip ? The car should run fine even with the ISV disconnected, you can try that. The belts can be easily inspected, but usually they only make noise, or if they are loose, you can tell. Doubt it's the alternator.
