ok, so in my car from a stand still i am in 1st and i accelerate 100% throttle and then i hit 4-5,000 rpm and the power coming on just freezes but the boost goes up and the exhaust starts popping. If i take foot of a bit say lik down to 60 - 70% throttle and then ease it back on it over comes this problem momenteraly it also does this is 2nd. As you can see this seriously hinders the performance and you help would be appreciated. I think it is a coilover problem and i have read and search and found other topics that seeeem similar but not totally. the mechanic noticed it to but said would look at it next service i would just like to know what the problem is before i go so iam more familiar with it when i take the car and know what the possiblities could be.
Thanks in advance!
