I love to mod. My m3 is modded to the hills as there is a plethora of parts to chose from.
I have not been able to find on Google or "search on the forms the following.
- Custom software that is plug and go (Other than URD but requires tuning)
- Underdrive pulleys -(if you have leads for them other than URD let me know)
I called Powerchip which is the company I use for software in my M3. I talked to them about making software for the new Tacoma's and they really seemed interested. If you read this and are looking for software
Email them and let them know they should look into it.
