i doubt it will be free... who is doing the install? and why not GIAC? if you were gonna go GIAC i could possibly get you a deal on software. crazy not to go GIAC if you have to buy software.... GIAC makes hella more torque then APR.

you need to check out sport compact 2007 challenge and see the GIAC powered S4 that won the challenge over loads of cars like: turbo supra, c5, 350z, m3, etc
