Hi All

I have a UK MY00, with a Decat as the only mod.

I had it for 3 years but recently when I am accelarating it seems to 'flutter' when on boost - rather than a smooth acceleration. It's better when on full throttle than part throttle.

I have the original MAF, do you think this might need changing?

Cheers

i had this problem on my car. does it fluctuate when your giving it a bit and feels like its building up in stages? do you have a boost gauge fitted if yes whats it showing?

 

Hi

Yes it seem build up. It's almost like the Turbo is very momentarily (fractions of a second) having it's boost cut, and it make the car slightly judder.

No boost gauge on my car. How did you fix yours?

Cheers

 

Is it all the time, or more so when its cold?

 

Hi Chris

It's all the time . It's not really bad yet but I want to nip it in the bud.

 

Hi,

I think mine is similar, its been that way for ages but i dont think it has always been...

interested to see what people come up with, could be down to the decat ??

 

Sounds like boost surging to me. Could probably improved with some mapping

 

Hi lunar,

do you think this will be less noticable with a dawes device controlling boost?

Cheers

 

well i cleaned my boost solenoid which seemed to help but its mainly caused by the de-cat. go for the cleaning first if its still there you need a re-map to sort it properly

 

Not sure Nicky. I currently have this problem on my MY03 STI and I have been assured that it can be cured or at least much improved with some mapping

 

Hmmm guess i'll have to live with it then. Having a phase 1.5 ecu puts a re-map out of the question....
