That boost gauge isn't in the right color... I'd have to pass on that car for that sole reason. JKJK
Seriously though it sounds like a lot of handling upgrades, so if you enjoy corners then it looks like a good list of upgrades. If you were hoping to dominate the drag I would say that is a poor mod list based on the fact that there is very little in the ways of power adders.
Frankly though being confident in the condition of a used car is more important to me than the mods it had on it.
One thought: if the car currently has an stage 2 map in it, did you receive the Accessport that is married to that ECU? You won't be able to just take the car to go get it tuned unless it's been unmarried, or you have the Accessport it's currently married to.
