m880, we used to use Dave at B&G, now A 2 Speed and I would recomend NOT using them to flash your pcm. I would be happy to send you photo of the pile of junk pcm's we have with their sticker on it, each costing a pcm plus $400...it just got too expensive. We are using soft flashes now, with SCT tuners as the bench flash was just killing a bunch of good pcm''s. They claim hardware instability but I think programmer error. We would get them back and they would work good but no oil pressure or a CEL but no codes then send them back and then they wouldnt shift correctly, send them back and now have some other issue, send new pcm and no gauges, send it back and gauges but wont shift and over and over ....pm me for info on a really good sct tune that you can update for better fine tuning with wide band or when you add new power.
