Diablo makes a Predator tune.sure Comp Cams makes a aftermarket Cam.seen headers think they were KooKs.air intakes all over the place.the new mustang 6 cyl for 2012 has 310 hp and get 30mpg highway, 0-60 in 5 seconds at 3600 lbs,not bad.I thought bout putting that 3.5 in couple of years ago the junkyard wanted 1300 for one with 33,000 miles.i thought from the beginning that is the motor they should have used.with such a nice outside the motor is far to exspensive to upgrade.$2000 headers,no intake manifolds that dont leak,cams are $1200.still aint hitting 300 hp.
