Default Engine bucks at full throttle let-off
The car has been sitting for a while and after driving it today I noticed that any time I let off of WOT, any gear, any speed, the car bucks for a split second. It only happens at WOT and even if I try to let off slowly it still does it.
I was figuring the EGT's are to blame. Any thoughts?

Check your DV lines and wastegate lines then go EGT

EGTs were the culprit in my case.
