After 1300+ dollars, sounds like truck is worse

I wanted a little more Azz to pull my racecar trailer. I installed a bunch of stuff, now I have what appears to be surging, sounds like birds flapping there wings, when i get on the gas hard (whenit is floored it seems ok).
So, I haven't made a pull yet, we got rained out last weekend, and I am out of town this weekend, but it apears after what, 1300 buck, i went backwards. Truck pulled fine before, I just wanted a little extra. WTF

Input is welcome, thanks

Oh, before upgrades, no surging at all
Now when i get on it, rolling on the throttle, not stabing it, at abou 12 psi it starts to flutter, and auge flutters

It was fluttering before, you just hear it now because of the AFE. It is probably a bit worse now due to the chip. You need a ATS ported compressor housing to correct this or install a wicked wheel compressor.

but before i could hear the turbo spool up and never heard it flutter.
I priced one at ITP, 399, are there any others. This can be done without removing turbo.

ITP would be your best bet for that...

You could also install a 1.00 exhaust housing and a WW, those together will get rid of surge 90% of the time.

Yes the ATS housing can be done with the turbo on the truck, but its much easier to do it on a bench.
