i feel like i lost 30rwhp :( please help guys

the last mod i did was the Xcal2 with 87 tune as most already know.The car was runing great , although i didnt feel any gains.maybe little but not noticable.Well i tried to flash many different tunes to get the best autcome.So finally i went back to the 87 tune because i had no pinging problems with it.Now my car feels like its lost Power ..20-30rwhp . I dont know it might all be in my head.But the car does seem a bit slower then it was withought the tune.
My car is an 04 with only 24K miles on it.It was runing great before all this.Any ideas ??

I guess the car was just sleeping.I did a couple of hard pulls and its back to normal.I woke it up , and raced a cammed 2000GT and full bolt-on, yah yah i got smoked that guy must atleast have 300rwhp , i got in his car with him , and man that thing really pulls "HARD" I'm surprised he didnt beat me by that much of a distance . But thats good
