I have been working near 10 years in turbocharging the 2,3 8v and 16v, I am more into performance rater then if mosselman or x makes the turbo or supercharging kit. If I had a Mercedes with a Mosslman probably I will keep it and improve it (efi-intercooler) just to keep runing 7psi not more. For me it's a little hard to inderstand how these kits improve the performance since don't have a clue how does manages the fuel enrichment, when I made it with K- jettronic, kE and motronic I end up making too many custom parts and for just runing 7 psi did not make sense anymore, that's why I used Megasquirt 3X ending up with much many features and advanced tuning and performance, I have a lots of respect for the people who designed the Amg's-mosselman etc etc. I would really like to know the list of the kit made by mosselman, I have some pictures of one brand new that was for sale but its had parts too basic and don thing it's the complete one. You have some really cool cars guys, keep them like that.
