im not sure if this is normal after i got my car back from the shop it seems if i punch the throttle down my car bogs hard and gets in and out of boost and bucks alot but if i build up boost it wont bog is that normal? sorry if its stupid it never did it before the retune

 

are you in like 4th gear going 20? and then you punch it?

 

No I can be going like 45 50 drop into 3rd punch it Nd it will Buck hard

 

It is probably how you are shifting the car, if not check for a boost leak.

 

Found your answer. Get a new tuner.
