I did the P.I. swap Heads,Cams,Mustang Intake,Professional Products Upper Intake Plenum, And 75mm Throttle Body It does not perform like it should and it misses every now and then so I thought maybe I would need a different tune there is no dyno around town so I cant get a tune that way any suggestions.

a/f should be the same regardless of airflow, which the MAF will read. Sniper's special forces will allow you tweak your a/f ratio to your hearts delight. SCT can mail you a custom tune. I really like my Special Forces. For performance, double check your vacuum lines, clean the MAF, change your o2s and fuel filter. The 20-30 hp you picked up shouldn't feel like much in a 5000lb truck unlike a thousand pound lighter car.
