Ive been looking for this anwser, sorry if i missed it, can you help me either way? I have a 03 ep3 swapped with a k24a2 and k pro'd. Right now it has a suuuper advanced tune for 100octane, and its like $8 a gallon here. I downloaded the k pro tune program and i noticed you have to choice a veh befor you pic a motor....and when i look at the stock tunes, theres nothing about swapped cars....So basically do i need to start off by choosing "tsx", then go to "k24a2 tunes"?
