I have a KO3 GTI that suffers from this since having a custom map put on at the weekend, going to change the DV to the revision D piston type as I'm still running the standard valve to see if this cures it

Guys,

I never realised this was on here. If you look on SCN, there are K03s cars that do it as well as K04 cars (also seen on this thread), and several dont have Revo Software.

Also, my car (early 07) does only has the flat spot intermittently, and funnily hasnt done it for a good month or two now. The S3 I know of (also early 07) has the flat spot permanently last I heard.

My flat spot seems to have gone now too  :stupid:

i sometimes get it in cold weather!!!

but i agree it seems intermittent. had it before. went after the new remap, came back but has gone again.  is it the car just being slow to adapt everynow and then to colder air maybe??although why is it always at the same RPM

still working on it, but if you are close to APS they could be the perfect guys to solve this issue.

are there any dyno graphs that show this flat spot. is it just a momentary drop in power or severe. i think mine is just a misfire tbh.

Boost drops, and the picks back up again after a while.

have you seen this on a dyno lot though or in logs or is it just an experienced thing.
