3 stage intake help with tune in the GTA please

[One28i]

hello, was wondering if anyone in the GTA has done the tune on their own? I finally got my 3SI put in myself (4 years of courage, 1 year on shelf after purchase, 2 evenings from start to finish for the hardware install). Ended up using the PVC hoses, didn't crack any plastics thanks God. But now comes the stuff I have no clue on, getting a 30i tune from a 130, or 330, of 530 on to the car. I do not have a cable, or the which software to use. aside from the PE muffler, rest is OG. help / guidance welcome.

thank you

I have done it on a friend's e90 328xi. Just follow the guide here: https://www.e90post.com/forums/showthread.php?t=1736657
It really explains everything you need to know step by step.
The cable is the most important piece of the puzzle. Try to obtain a good quality k+dcan cable, like the one linked in that post.
Good luck!
