Gtrs Turbo Problem

[gtr jason]

hi has anyone had the problem of the gtrs turbos having chater under 4000rpm then clearing after that what makes this happen and how do you fix the problem thanks Jason

sounds like turbo shuffle. I thought it could be tuned out. Tends to happen with turbs spooling up (larger comp wheels) air moving at continually different rates through AFMS.

I think thats hows it goes. There are a few threads on the topic.

Theres the money question right there. There have been a number of suggestions on this isse and i've yet to read of a definitive fix. The fixes range from issues with aftermarket BOV's, changing to bigger cams to promote flow, lack of or poorly tuned computers, and running a bridged manifold. Search and search again, Good luck

Bridged exhaust manifolds are what the Brits are talking about, and some tuning, cam adjustment.

What BOV's are you using?

It is normal for them to do it, even 2530's do it aswell in some cases

Jason, Im pretty sure Paul (DirtGarage) had the same issue and CRD sorted it.

I could be wrong, but it might be worth dropping him a pm.

i had this problem a while ago. so i got rid of my aftermarket bovs and put my stockies back in and it was significantly reduced. Although in 5th gear under load up a hill it still did it hear and there but only a little bit. So I got a Power FC and got it tuned. Even though the guys at UAS reckon they couldnt tune it out, its gone for good! No more turbo shuffle at all since the tune.
