It is easy. Just get a Livernois Motorsports 93 Performance tune! That is right, I didn't say an e30 tune or a ton of parts...JUST A 93 TUNE! Even with REALLY bad DA (~2600-3000) the GT350 was struggling! Don't think so? Watch.

If you own the top dog Shelby GT350 Mustang, you might immediately dismiss that Focus RS staging next to you at the drag strip. Well, you might want to think twice if your Shelby is stock, because a tuned Focus RS recently held its own against a stock Shelby GT350 at a private track rental in Michigan. Using launch control set at 5,000 rpm, the Focus RS used its all-wheel-drive grip to get the jump and hang with the Voodoo-powered Mustang–12.88 vs.12.64. (On the next pass–not seen here–the RS actually edged the GT350 with a 12.7). You can watch the friendly race right here...
