ISO base tune for 05 obxt at with arashi td05h 20g 8cm, tgv delete, 2.5” no cat down pipe no cat up pipe, 750cc injectors and Cobb intake tube to turbo, basically stage 3. As I progress with this project I will add suggested items like a wideband or anything else users may recommend. I just need to get started at this point.

Thanks, Paul

hey paul, i was thinking about that exact turbo for my 05 LGT! anywho.
so you have 750cc injectors on an otherwise stock fuel system? stock pump?
also, IMHO you need to make a electronic boost controller and a wideband a top priority.

i know you probably want to go cruise your car, but think of it this way, you have added fuel the computer doesnt know about (injectors), added more air than the computer can control(turbo without boost controller), and no way for the to accurately see what is going on (no wideband). a base map will probably only help with the additional fuel. it will probably struggle to accurately control the wastegate and might not see a problem until its too late.
