So had an autox session today. The car started off losing power seemingly at random. I would push down on the gas and it would go for about 2-3 seconds then lose power for about 1 second then continue like normal for a bit. Happened in the straights, happened in the turns. In addition the temp when i was idling was 200 after the first run and it increased to 204 by the time i was in line for a second run. It was 64 outside and cloudy so its not a hot day and it was still early in the morning so its not like there was a lot of heat still coming off the ground. Checked that i was in the Cobb track slot and made sure all my setting were good. Same thing happens. Turned the car off checked the fluids everything is topped off and oil isnt milky. Got one run in that i was not noticing it too much. But after that it came back. I get to a big sweeper and as i turn it just starts cutting out and kinda sputtering.

Changed tunes to a Tune+ tune. Same thing happens but now it only does it in the sweeper and same as before cuts all power, its not hitting a rev limit or anything its just not going. I finally get it to start going again and it is fine as long as i am not on that one sweeper. I just gave up at that point. Went home and wanted to see if it would do it again like earlier in the day. Floored it in second down the on ramp and it did it just like always. No problems what so ever.

So im kinda stumped as to why it is doing this. I turned traction control on and off thinking maybe it was being super aggressive but it made no difference. That same sweeper just caused it to lose power. I have done this track many times before an nothing like this has occured

Intercooler heat soak maybe? IAT too high and pulling timing.

When was the last time you checked your plug gaps? The RS is hard on plugs.

It was pulling timing due to heat, how are you charge temps that hot? Mine max at 120°F and I'm stock intercooler minus the side plate. That's glued on.

Oh man im dumb and i didnt put that the OIL temp was at 200 and went to 230 not the coolant. Sorry about that and the late reply on this. From what i remember the coolant was about normal temp.
