Sorry to hear about your chip dilemma. I would just purchase an aftermarket chip now and be done with it unless you plan on modding the car and then burning one specific for your set up. You have choices....MarkD, Turner/Conforti, Midnight Tuning....I'm sure there are a couple more like eBay, which I hope you won't do again, but the 3 that I mentioned are the most trust worthy and in no particular order.
Good Luck!!
