A lot of things can slow the WOT response, over shoot or short shift - tip in logic is a PITA for example.
WOT table has to be adjusted to OSS - one will not work without another. RPM anticipation plays a role as well.
TCC schedule is also very important - again has to be adjusted correctly. Also how fast TCC locks since there will be no time to complete the sift with TCC being modulated
Nothing easy in those tunes hence some tuners charging 300-ish for locked tunes and won't send you any unlocked tunes even for 5 grand.
