The fact you ahve run one without problems doesnt make it the optimum charger to use.
I know of people with 240bhp cossies running on T34.63 (well everyone who bought an escos really) but a T3 would do the job better at that power level!
Jim needs to make his mind up on what power he wants IMHO
A correctly installed and mapped M62 should comfortable see his 260bhp target, but if he wants 300bhp or more than an M90 sounds good to me.
