Yeah, as Jimser said, your TMIC will be ok, but your turbo won't give you the 350 your looking for but I'm pretty sure your injectors will. You're looking at an uprated turbo to get the 350 you want with a remap of course. Your cats will restrict you as well, so you might want to consider at least a sports cat. A full decat is worth around another 30bhp but it wont be legal - hence the reason I went down the sports-cat route.
