I know its kinda stupid asking this question here...but I wanted some real answers. Also should have asked this first...but I kinda got blinded by the test drive so to speak.

--------------

I'm a very indecisive person, my wife can attest. I am coming from a 2016 Subaru WRX STi running stage 2. I purchased a 2015 automatic Mustang GT to replace it, I was kinda tired of driving stick as its cumbersome for me.

My concerns:
The stage 2 STi was faster than the Mustang stock.
Can I get better performance out of the mustang than I could have the STi?
Should I take the car back and go another route?

THANK YOU.

You made the right decision.

I appreciate the honesty, but can I get some help on the various points? Mainly because I wanna know what upgrades I have.

What does 'Stage 2' entail?

Are you talking about a COBB Stage II tune? If so, your Mustang GT should be about as fast/faster at stock. 1/4 time for a stock S550 GT is ~12.8 and 0-60 is 4.5. I'm reading high 12 1/4s for an STI with a COB Stage II tune with no other mods. (Unless, of course, the forums I found are full of crap )
A simple tune (don't bother with a CAI) usually puts peoples 1/4 times down to ~12.2-12.3 with an auto running in sports/race mode on the 2015-2017 GTs and low 4s for the 0-60.

EDIT: I also recommend getting rid of the craptastic P Zero Nero tires immediately if you have the stock A/S tires.

Get a Lund Flex fuel tune and a pair of headers. Car will be night and day. Should be way faster than the WRX.

Would be nice if the OP participated more in his thread...

Definitely take the Mustang back and see if you can trade it for a 2016 STi (w/ stage II upgrades).

Mustangs are pretty much as fast as they can be from the factory.

I agree. Once a subie guy always a ricer. I mean a subie guy.
