im sometimes having an issue with the turbo stuttering.
![](./images/smilies/spacer.gif)
standard ct20 turbo running 1.2 bar with a greddy E01 boost controller.

this only happens when its really cold or raning most of the time.

if im on the motorway in 4th or 5th gear and i just give between quater and half throttle the boost rises up fine intil it gets close to peak boost and then it starts to stutter.

it sounds like the car has anti lag or something when its doing it.

kind of like fuel cut is very gently alternating between on and off

(is this possible).

im not really sure what it is or how dangeorous it is.

it dosent do it when i turn the boost down either so for now ive just been doing that.

i dont think its the limit on the boost controller as that is set to 1.23 bar and nicely reduces the boost by 2% and keeps it at that level.

one thing ive just considered is it could be fuel cut and the boost controllers limiter conflicting between each other?

any ideas welcome, i dont want to kill my turbo
