I purchased the car about 8 months ago. They were in it once purchased. You could probably call Eric at TT and give him the order #. I believe it may be the number at the top of the chip, I'm not sure. I can tell you this-the car ran like a bat out of hell with them in there. Truthfully, I would have kept them if I didn't want 60's down the road. You might can run the numbers on the injectors and see what you come up with.
