To the point then, Just had the Astra MKII Turbo chipped and all was fine and dandy for afew days. The Engine is set to Over boost to 1.1Bar and then drop back to 0.9Bar.
What is happening now is that you Over boost to 1.1Bar and then slowly drop back to about 0.6/0.5 Bar bust only does it half of the time of the time. The car also really feels like it is holding back from what i'm used to...........
I know what i think the problem may be but really need a fresh perspective.
