Paul,
congratulations on your purchase - nice combo! I am interested if John gave yu any indicative cruise figures for the Sti and 915 combo?? I have been waiting with interest to hear about all the performance figures they have been getting with the factory model.
Anyway, welcome to the forum - I benefited from the wisdom and generosity of the people on here throughout my build and I know will also. Looking forward to your reports.
cheers
ross
