Tune-only, B58TU1 on 93 makes 500whp? I guess that makes sense as I believe I saw a S58 pick up 100+whp with just a tune, from around 488whp stock to 600whp. Revised B58 seems to make exactly 100whp less than the S58 whether stock or tuned. I wonder how they'll hold up over time. Pretty much every iteration since the N54 has some fun stuff to deal with later in life for whoever owns it by then.Yeah kinda sucks for them. Definitely will see more high power 21 Supra’s tho. Tune alone they hit 500hp! 550 with catless downpipe!
