I have very similar mods to my car. I have a MK II T56 with Typhoon CAI, K&N, Siemens Deka 60's and edit at the moment (250rwks). I have a wog cooler at home which I haven't fitted because I am waiting to do the hi flow cat and valve springs (don't won't to pay for retune) I would definately go the Siemens injectors. They are the best going around. I have been told the 968's can run out of puff whereas these won't. Valve springs is also a must mod.
