When were the plugs and coils last replaced? Link to comment Share on other sites More sharing options...

Made a rev limiter sound, farting noise when I hit 3k, sort of vibrating as the boost was escaping. Link to comment Share on other sites More sharing options...

Wen ever the car had been driving for a bit and I gave it it would do what u were explaining, it would kinda stutta and back fire, felt like I had no power. As soon as I told my tuner I was using bp he said it was sh*t and to change to sell, ive never looked back and the problem was solved. so give that a go if your using bp Link to comment Share on other sites More sharing options...

Made a rev limiter sound, farting noise when I hit 3k, sort of vibrating as the boost was escaping.ive had two different mechanics go over the car top to bottom theres no problems what so ever it seems to only have the problem after 10 min of driving when the car warms up, before that it runs normal.
