[QUOTE="alexgg2, post: 14635391, member: 81824"] if you really owned one then you would really know the cobra with simple mods will have huge power gains compared to the 2015 GT. Simple mods like pulley and tuner(about $500) and your making around 465rwhp. Obviously you never owned one and only looking at specs ford posted on these vehicles which was way underrated and proven by stock dyno runs. cobra terminators make about the same rwhp as the new 2015 gt.
