I had Limestone Auto Solutions do the MDS delete on my Durango SRT 392 (MDS is the 8/4 cylinder mode). This involves removing the front clip of the car, removing the engine heads, front cover, timing chain, cam, lifters, oil pump and oil pan (a big job).
I also had them change out the auto transmission fluid and upgraded the engine oil pump to a Melling high volume pump to prevent too low oil pressure during idle. They did a great job. Kevin, the owner, is really easy to work with. I highly recommend Limestone Auto Solutions. read more
