Wow, that's horrible to hear. My car is fully modded, but that's cause of the previous owner, but it runs and drives well so all the trial and error is out of the way. Before I do any modding of my own, I plan to have me a decent little car with good gas mileage. I plan on putting together a compound boost set up
but I hope you get everything resolved, and don't give up on your Mach!!! lol
