I cant be bothered reading this whole thread but just to let you guys know, I work for a ford dealer, and last week we had a BF turbo come in with a massive engine let go ( threw a rod, had fist sized wholes in the block and sump) we had one of the Ford guys come down with his little gadget, which isnt a wds/pds or IDS ... but it can read PCM history which showed us that this PCM had been Flashed 3 times, none of which had been done at a dealer, since my dealer was the only one to service this car, also the car had been in the previous week with a monza cooler fitted (which amazingly had disappered when it came in on the tow truck).... Just thought id let you guys know, although im not clear if this can be done on BAs as I didnt ask....
