When I step on the gas and kinda smash my car and when my turbo spools it sounds like its sputtering. This is actually my first turbo car so I'm not quite sure what's going on. Mods turbo back. Spt intake. Turbo xs re circulating bov. Stage 2 Cobb map. It does not sound it's spooling smoothly.

Any opinion will be greatly appreciated.

Thanks guys.

Check the hoses on the turbo and the vacuum hoses if they popped out.

Ok cool. Anything else should I look at?

If the hoses on the turbo and vacuum are ok, then check the turbo if there's cracks on the housing and bent fins on the compressor wheel.

Oh damn hopefully its only loose hose or vacuum leak. Thanks man appreciate it.

Gotcha. Ill check the clamps on the tmic.

FYI, you cannot use an SPT intake with the Cobb maps. Custom tune required.

Also, ditch that TXS valve. The TXS H-Line is well known for being crappy valves. They very often leak, and that could actually be your problem.

Gotcha it came with the car and it did not have the oem box. Yeah I was actually thinking about taking the bov out.

So update. I put the OE bov back on. Checked all the hoses and tighten all the clamps. The car runs better and picks up faster. But there still a little bit of sputtering at about maybe 5000 rpm. I'm planning to buy a cobb intake and replace my spt.

I had the same issue when I was on similar mods with a K&N typhoon. Once I went back to the stock intake the problem went away.
