  6. 2012 Mustang 5.0 - To wash or not to wash the underbody after winter

    Show & Shine
    I've long held it to be common sense to wash the underbody of one's car after any winter where the car may have driven over a salty road, but some of the comments on various Mustang forums have said it's not so. I've even heard it may do more harm than good, wetting the salt and pushing it up...
  7. Anyone running the ROUSH R2300 Phase 2 625 HP Superchargeron a 2012 GT?

    2011 - 2014 Mustang GT Tech
    Hey. I was just wondering if anybody was running the ROUSH 625 HP Supercharger on a 2012 GT (automatic tranny). I'm seriously considering getting a ROUSH but I wasn't sure if the 625 HP was that much better than the 575 HP. It runs $500 more so I'm not sure if the extra 50 HP justifies the...

    2011 - 2014 Mustang GT Tech
    Hi guys, I'm going to be installing the Magnaflow Competition catback exhaust on my 2012 GT this Wednesday. I was going to order a UPR Xpipe and delete the cats but decided against it, mostly because I didn't want to screw with the warantee too bad. I read on some earlier threads that the...

    2011 - 2014 Mustang GT Tech
    I just bought a diablosport Trinity t1000 tuner from a coworker. I later realized on that there is a t1000 for 2011-2013 mustangs and one for 2005-2011. Sure enough I then realized the one I have was for the 2005-2011 mustangs. My question is, obvioisly, will this tuner work...

  15. Exhaust Question 2012 GT

    2011 - 2014 Mustang GT Tech
    I think I've narrowed down the axleback exhaust set-up to purchase between the Roush and FRPP GT500. I've read good things about both kits but I havn't heard any of them in person, just in countless videos. They both sound good to me and for the money, the GT500 seems the way to go. I'm...

    2011 - 2014 Mustang GT Tech
    Hey everyone I was wondering if I would get any performance gains from dropping in a K&N high flow fliter but no tune. Its the same filter that comes with the FRPP power pack 1 for the 2011-2012 5.0. When you order it through ford you also get a computer retune, so is the re-tune neseccary or...
