I don't have a laptop but have a freind with a Subbie who also wants to get an EMS and he's considering getting a TurboXS, would I need a laptop or could I use my desk top?If I pull out the ECU.

Where would I find the "free stuff"?

Also can you use the same tuning say from Turbo XS on 2 different cars or can it only be used on the 1st one you install it on?
