nistune has been out along time, they have several different board types an support a much broader list of cars then calum.. we started hearing about nistune when calum disappeared because the aus/nz guys let us know about them, not to mention nistunes an ACTUAL BUSINESS not some guy doing this for fun.. there are several certified shops here in the states that can sell/install boards for you and even tune your ride..
dont think im dissin calums stuff, he helped us alot.. thank god for him.
if you just want a ve tune, you can get it done for 300, thats board + install.. you can send them a bin to throw on for you so when you get it, its good to go..
then you could find someone who has nistune to help you modify the tune an stuff in the future, OR find a shop that has nistune..
HELL i'd even change the tune for you if you wanted to send me the ecu, i'd put it in danfivetens car, change the tune an send it back as long as you paid all shipping costs
its the usb cable and software that put nistune in the 600 range..
