It was a series 2 auto(neo motor) It had 3" turbo back exhaust, pod and 12psi, shift kit and sway bars.
It's more that it lacked torque, ie on boost up hills, all good
Off boost, slight rise in the road, gutless, down change a gear
I found that unless I was towing on the flat above 100k I'd just hold it in 3rd gear
The rear end felt fair average with the boat on it. Not ver heavy, ie 950kg on the trailer with spare fuel and ski gear, but the long ass trailer made the back end feel like poo
