Hi, I have a laptop with LT1 edit and the PCM. also have Tunercats for another PCM. I tuned the LT1 edit for my 383,A4 3:73. datamaster is also on the laptop. I also have the cable ( OBD2 conn. but PCM 's are OB1) I am done tuning my car since I parted it out. So if any one is interested, Everything for $500. Ray 917 348 2716
