350 MAG MPI Engine Computer 2003 20v - available

[PromoTige]

I have a part with about 120 hours. It was sold to me on my 20i and created an alarm every time we hit 35 mph or above. Once switched to correct computer for 20i rather than 20v everything worked great. Interested in this item make an offer. I was told it sells for $1,500.00.
