epools Posted February 7, 2008 Report Share Posted February 7, 2008 Has anyone with an 07/08 GT500 used any M.S.D. products on thier car with good results. I have used them on many older cars with very good performance gains. I would like a testimony from someone who has actually used them on this car. M.S.D. lists some parts for this car and after talking to them(M.S.D.) I learned they have some more products in development for the 4 valve 5.4 Ford.
