Stutter Under Load

[Skylinestyle101]

Hi Guys

I have just got the car back on the road after a 6 month wait. I have just changed the spark plugs as i was getting a missfire due to finding some water around plug 3. The new plugs have cleared my missfire but i am finding now that when i get into the boost during rolling power down. that as boost pressure builds i get a stutter that sounds a bit like the bov or wastegate opening. I have also noticed that my injector whine sounds different as well. Can anyone please give me ideas as where to start. During normal driving the car runs fine it just when i put my foot down.

What gap did you set the plugs at?

What's your setup?

How much boost?

Etc

Could be stock ECU having a fit if your running higher than factory boost levels or to large a gap in your plugs/ non ideal plugs

hey mate

plug gap is 1.1 car is running stock boost and intercooler setup. has pod and cat back exhaust also. i am goin to try cleaning the afm and check that all is connected correctly

as for the injector sound. it sounds like static but i havent noticed any change in fuel useage or general drivability.
