There is a negative correlation between VO2Max and VLaMax. There is minus in front of the 136.
-32.48 - 136 * VLaMax + 6.449 * 70 = 330 => VLaMax = 0,654
If VO2max goes up then your FTP raises. You are able to bring the same O2 to less body mass as result of body weight loss, which improves performances. If you want to keep FTP stable (not a realistic assumption) then you would need bring VLaMax up.
