@Reacon Thank you, this really helped... i removed DragDead, FF Mod and RealLifeMod and the slow mo was gone!
Thank you a lot!

@Reacon I am using DragDead, Firefighter Mod, RealLifeMod, Simeon Repo Missions, TonyaTowMissions....

So everytime i go into aiming the screen turns greenish and the time slows down...just like the bullet time from Michael.
I have no clue where this thing comes from, but id like to remove it. I basically use most of the mods Jeff Favignano linked under his videos, and no Enhanced Native Trainer, just the simple native trainer.

I have seen some Pictures of The exact model I am looking for, here on GTA 5 mods. But I can't find the model any longer. I have pretty much tried everything. [something like this] (http://www.ff-gaming.at/Administrationspanel/Bildergalerie/Galerien/240/Foto30.04.15123722.jpg)

PS. I am not looking for a firetruck paint job, just the FMX model as a Firetruck in general would be nice.
