i have a 94 formula. i bought it 2 months ago and it already had a gm performance cam, and injectors. id how big he didnt specify. its an auto tranny with the transmission perform button. when i go full throttle at the end of second gear i have to back off the pedal a lil for it to shift... and its also acting like its lagging past 5k. anyone had this problem b4? i flushed the fluids and all to clean the filter(thought that would help) but it didnt. any suggestions?

 

Could be a trans or tune issue with the mods. I would suggest you get the tune looked at first
