Cam specs will very by the 1000.00's no problem there,as far as the difference from your current cam cant say.

mine is 242.6/248.7-608/614-110.2. I think they all vary some. Tune again.

Cams are never gunn be "exact". As for your tune, it'll prolly idle bad, but should still run ok once your going. It'll deffinatlly need to be redone to gain the max from the cam.

As the others have said, cam specs almost always vary from what's advertised.

I ran my T-ReX with the stock tune for several weeks and had surprisingly few problems, so you should be fine until you can get a tune specifically for the new cam.
