That's a nice looking bg galant and I hope it goes to a good home. I mean no disrespect but I have doubts that it makes anywhere near 450 hp with 720 injectors, a chip and safc. I would venture to guess that it makes about 300 whp. That's about what my car made on 91 octance when I first got it, only difference is I had a vpc and a much bigger fuel pump.
Good luck with the sale.
