predator performance tune engine bog

Ok so that sums it up I have predator U7198, got it about 2 weeks ago havent changed anything. In 1st it bogs anywhere from 1350-2000 and then again in 2nd around 2000. I have the latest update which may be what caused it cuz on my previous version I did not notice a bog or anything so I can assume it is the timing but if I upload it here i still want the tune to be better than stock... Can anyone help me out? 2001 firebird formula 6 speed, lid, smooth bellow, catback.

nothing in those tunes has changed for quite some time, I dont believe the update would change anything...

ya im sorry for makin a big deal about its just when i installed the tune is when the bog started but checked the codes, o2 sensor was bad no check engine light? anyways replaced it put the tune back on everythings good.
