damn speed cat how much weight do you wanna take out? well I don't think you can take out enough to effect your tune.
load amount effects turbo spool up. the more load the harder the turbo works. less rotating weight /rotating mass gives faster spool up.
less weight = less load = slower spool up times. This is why you build boost easier in 5th, and much slower in 1st. If you can remove a very significant amount of weight, it can affect your tune as most tuners dont tune for every psi at every RPM point. It really depends on how much weight and how shitty of a tune it has.
