use the 5,000 and put it towards the maintenance and repairs. if you'd like some performance software for the DME and EGS, i can send you a programming package and i can program your vehicle remotely. the package will cost $85 and i will send you the cable and you can keep the cable afterwards. all you need is a high speed internet connection, laptop with 2.0ghz with 2gigs of ram and a stable power supply device.
