Can anyone tell me what the differences are in these two tuner tools? Can I get different profiles with the pro cal from Ford or would it be better to go with the X-cal?
That is, all things being equal, which unit will give me greater flexability and access to more tune profiles?

Thanks guys!

 

i'm pretty sure the pro cal tool only
holds one tune and there is no
user adjustability while uploading

 

Correct, but there is now a new Pro cal tuner just out similar to the SCT unit.
