1. A91 & Recent 2021 Impossible to Tune / ECU manufactured after 2020/6 is locked?

    ** EMERGENCY POST ** We were asked not to talk about it, but it’ll end up going public soon anyways. Upon earlier this week, we received our first A91 (that i know of in the world) to be tuned. Sending his ECU in to us to be unlocked, we came across some information thats never been seen...
  2. B48 - forged?

    So B48 is said to be a B58 with 2 less cylinders, so it means there are forged pistons, rods, crank and closed deck head too like in B58? Curious in terms of reliability and potential 300-350+ power mods.
