Tons of turbo bark and surge

[08Monster]

Recently installed a No Limit stage 2 on my dereted 2014, ran it with my tunes I had, and had a bad surge when cruising about 60, or when going down hill. Constant cycle from 2-10lbs of boost. Got new tunes for the intake, still surges, and barks my turbo ALL the time. Under light acceleration (5lbs of boost) I can let off and it'll bark. When I come to a stop, it will literally bark the turbo for 3 full seconds, going tu-tu-tu...... What the hell is the deal?

Is the mass air flow sensor pointed the correct direction?

You said you got new tunes with the intake, have you tried your old tunes since?

It only mounts in the intake one direction, so it must be right I assume. I noticed the surge with the old tunes, texted Mike and got the new ones, no change at all from old to new. Barks like mad, I don't even want to drive it. I'm sure I've done lots of damage to the turbo already.

Sounds like the turbo is going? Stock twin scroll?

Stock turbo. It never did this before the intake. Why would installing the intake make it do this? Never had an issue before.

Well I'm just saying, you mentioned white smoke coming from the exhaust too, sounds like the turbo...

You could have the entire tube backwards

That's what I'm thinking...I have seen several reports of this.

I pulled it yesterday and checked, the flow arrow is pointing to the engine.

Well if your turbo ends up being the case, I've got mine for sale.

I would imagine it was already acting this way and the intake just made it more audible

That's a good point. What can I check to see if it is the turbo?

What's the price on that?

But, my turbo never once surged before the intake, now it's constant! It's gotta be the tunes. I'll call Mike tomorrow and get something lined up. I gotta change something

I have IDP tunes also on my X4, I'm loading the load first tune now, than trying those. If those do it also, I'll blame the turbo. If they don't, I blame the tunes.

IDP runs flawlessly. GHead seems to have more power, but these don't surge or bark. Definitely an issue in the tuning.

It's the tunes. I pm'd you.

MY 2014 does this as well every time i cut it off and when i let off after a hard acceleration . im running ******** tunes with no limit stage 2 intake. I thought it was normal. Should i get my tunes tweaked? Thanks guys.:wtf:
