Besides the fact that the boost on my green seems to be coming on way late and that my timing seems a little jacked, what could be causing this breaking up?? Even though knock is not shown in this map, it was not knocking. This was just a 2nd gear pull while trying to get things tweaked. I have noticed this breaking up in different gears though. It does it for a short burst, and recovers. You cant really see it in the RPM line but the log does show it drop down slightly and recover. Spark plugs maybe?

 

Fuel cut? Spark blowout?

It may spark interest if you change your title to something specific rather than a catchall.

 

Tighten spark plug gap and see if it helps.

 

Thanks guys. Mplspilot what RPM does your green hit max boost? Thanks again for your help on multiple issues.

 

I'm currently on a IX turbo.. I don't remember, to be honest, around 3900-4000 in 3rd gear, 28psi. If you hit it much later in 3rd or in 4th, something may be going on with the wastegate. It's may not be closing properly. Some of these lose their WG flappers through exhaust... Try tightening the WG arm first though. And do a boost leak test.
