Re: Towing??
IMO The two main issues are probably
1-Transmission, the stock transmission is overstressed even before towing.
2-Rear Springs, are lower than stock so the rear suspension travel is reduced.
Another issue would be the additional heat caused by the turbo, can the cooling system keep the oil & coolant temps reasonable if towing up long hills and the turbo is in boost for prolonged periods of time.
To tow,1 & 2 I would address and would be mindful of prolonged periods of boost. That being said, I plan on someday use my Sy to tow a small boat.
