Welcome to the forum. Good that it’s all yours. Let us know what your goals are with your mods. There are enough members that have done it all. Big and small mods, we can also suggest what does and doesn’t work.
Like Clarksunx, I just picked up a 2009 Black GT with 122K miles about six weeks ago. Before I start mod'ing, I thought I would take it to a local hot rod shop and ask if they will run some basic engine and transmission checks before I start dumping money in. GT seems to be running strong but, they'll do a compression test and a leak test for the heads. $300 for this. Next I want to get the transmission eye ball'd if you will.
