Hi all, Having a few issues on my jap my94. I have a bailey dump valve on it and it sounds ok about 300orpm but after that it sounds horrible and fluttery (if thats a word). and about 4k rpm it sounds like a dog with kennel cough and then blows off.

I tried it on my mates MY98 and it works and sounds amazing....

so if anyone has any ideas please let me know, as i have read on here that strange things happen when your wastegate sticks and could it possibly be the reason the car struggles to pick up in 1st and then takes off like a bullet

over to you ...
