I know this has been talked about before but i never really found the answer so figured id get some opinions..
Like title says whenever im boosting at partial throttle (5-12 psi) feels like the turbo is sputtering because i feel it in accel. But at 0 psi and wot pulls smooth. Any ideas?
mods: ams intake
TBE
FMIC kit
stage 2 ots ams tune
stock bov incase that matters??

 

since u have ams tune... id ask them?

 

Do you mean the stutter when you lift a little when at part-throttle?

 

This

 

same thing happens to me id like to know. except i think its my ssqv acting up cause its wanting to blow off before i lift off the throttle enough to stay at constant speed and its making my car jerk alot

 

its basically without letting off throttle, keeping constant and consistent pedal pressure. just like what rpf1 said. And about the tune i should ask cobb? because its an AP tune. and im sure plenty of people are running very similar mods as me on here.

 

What gear are you in? I know that if you are in 5th and running at about 2000rpms you will get a flutter from the BOV especially when you start to accelerate. If that is the case just don't drive at 2000rpms while in 5th.

 

I had the same problem. I had a Greedy bov and as i switched to a stock 9 dv the problem stopped.

 

this.

if you want to get a complete picture, log accel pedal position, TPS, MAP, and your wastegate duty cycles.

usually, this only happens to me in 5th gear around 40-45mph (although if I went 25mph in 4th gear it would probably happen, too)

 

^ good idea ill try that. and could it be my bov??

 

The BOV should be fine just change your driving style.
