I am sure there are hundreds of threads that can answer these questions but I cant remember/ retain everything I read for 3 weeks so I will just ask everything in one post and hope for the best, BTW I am a happy new ford Mustang 5.0 owner coming from a dark chevy background and do not know everything about everything that has to do with mustangs so please, if possible give "simple for idiots" answers. 1st, I have always loved the sound of a mustang and want nothing more than to add some power and voice to my new 5.0. I have a budget of about 3k so please give some opinions on "bolt-ons" that will give the most bang for 3k.(please include part numbers/ links and even your own personal aftermarket setup with before and after HP/torque readings, if its not too much trouble- Thanks in advance) 2nd I have read a few threads that are a bit nerve racking about some problems people are having with the new 13' GT's, ie.. (#8 cylinder when tuned, which I would assume might be part of my $3k in upgrades, MT problems, clutch issues, etc) Please indicate/ describe any known problems and ways to avoid/ prevent them from happening. I want to be prepared for these issues before they happen to avoid confusion and also have some general knowledge so that if/when the problem occurs, I'm not going to the dealer and having to take out a second mortgage to cover repairs that have nothing to do with the initial problem. 3rd and last I bought the 2013 5.0 with recaro seats and track pack. My question is- does the track pack make a true difference from a performance standpoint? I know that it helps keep the car cooler which would in turn make more consistency. But does it do anything else or was it a $2500 waste? Again, thanks in advance for any feedback. I appreciate everybody's opinions on this subject.
