my Power duals and hi-outputs ran just fine with fuelpak and SE A/C

iwouldnt pay for a dyno tune unless i build the engine up. the 5 hp difference between a dyno and one of jamie's maps (or the like) isnt worth the extra $$$

 

11 FLTRX Power Pac option which includes 103ci and oil cooler among other goodies. Add SE 255 cams, SE Ventilator AC, SE Race Tuner, and V&H Power Duals w/ V&H High Output Mufflers. Holds tune fine, like many others have stated, find another shop, my parts are the same exhaust as mentioned...

 

Tuned just fine on mine with the PCV from FuelMoto and their tune.
