New turbos, boost surging/oscillation while accelerating

Bme30 · 02-08-2013, 07:03 AM

So I got turbos replaced under warranty. Very thankful. Just having some issues and need help. As the thread states I'm getting surging or oscillating while accelerating.
Any ideas would help.
Edit. The car is stock besides downpipes. No other mods.

Quick question, you have downpipes and no tune and they changed your turbos under warranty?

No changed with stock dp
Was surging with stock dp on. Had my dp put on yesterday and the surging is still there.

Had a fuel pump plausibility code too. That was before the dp install. I got the car back earlier this week. i replaced one of my boost solenoids before the turbo install thinking that was causing my underboost. I'm going to replace the other one too.

I had somehting like this a long time ago that turned out to be a damaged o2 sensor that was not throwing any codes. Pretty sure mine happened from installing and uninstalling DP's for dealer visits at that time. Just a thought...

Did you resolve your problem ?

Check vacuum lines. Could be a small boost leak

I think it could be my forge DVs... Maybe then don't open/close properly

the issue has been fixed for a long time. The stock waste gates were not adjusted properly. Has my indy shop fix everything and now the car is a champ. Been running strong until a recent injector failure lol But the car drives great.
Everything fixed running e60 on a backend flash on 18psi. The car is the happiest it has ever been!

Nice - I think my WGs need calibration too, would you know how many hrs labor they charge ? Its a pain to do the front one I guess

I'd like to know also, how do they adjust them? Is there a DIY? Or do i just change my settings on JB4? I have that slight boost spike/surge feeling but no loss of boost just feels a bit odd. Nothing too major though.

Bme30 · 07-14-2014, 03:15 PM

they charged me like $150 or something like that. But I never needed to adjust the jb4 settings as what came right out of the box has worked perfect for me!
