im having problem with my transmission. when in hard acceleration and i shift into 2nd and well all the way through 2nd it seems really underpowered and almost like its bogged down but then 3rd and 4th are fine anytoughts or sugestions. i have a diablo tuner, 4:10's, MGW short shifter, K&N CAI, straigt pipes, and 18x10 FR500 wheels in the rear w/ 275/35 rubber on em.

 

No ideas, but please make the picture in your sig smaller.
