Hi everyone,

My problem is that when i put my foot down and the boost gets to max the car really jerks as if ive hit something. If i put my foot down and ease off a little before max boost it continues to accelerate. It seems that on the max boost it only uses half of the gear. No other probs like idling or hunting. If it makes any difference the car is running in KM.( getting a convertor in next week or so)

Any advice because i cant enjoy the car to the full.

You are running too much boost You need to turn it down. This happened on my 'grale and the force broke the transfer box

 

The boost seems to work ok its just when you try and get all of it in one go. The link above about the problem with fuek seems to fit the bill. I am running box standard unleaded.(school boy error) i will try this first, if that dont work i will look at turning the boost down. Thanks for the advice.
