Struggling to tune Sequential turbos in al rima

When im tuning the sequential turbos, regardless of what motor or turbo config (1 or 2 pairs) i always get this bump in the centre where i assume it swithes from turbo 1 to 2 and just cant seem to tune it out no matter what i do, i understand its still a beta, but was hoping for some tips or maybe someone knows if this is just a bug.

Also on a slightly separte mote, i still have the option for dual exhausts when using single pair of sequential turbos.

That bump is always gonna be there, and that’s intended, as it apparently is so IRL.

That bump is from the shift from one turbo to the next, it’s unavoidable.
