well, the chip tuning is a ecu tuning only if its the $300 ones that actually plug in the ecu directly. otherwise, the chips from ebay that go for $20, are pure garbage.
I didnt know much about these, so i took my chances and bought one and as soon as I started my cougar, the idling got all screwed up and my check engine light went on.
DO NOT BUY ANY CHIP THAT PLUGS INTO THE IAT SENSOR!!!
