Hi, i hope someone can help me. I got admin tuned a few months back and ever since I got tuned my car has been feeling sluggish. Let me explain better. When I first would get into my car and drive everything feels good it drives normal and it’s very fast but 20 minutes in, it becomes very slow and I can be flooring it all the way down and the rpm won’t spike up or gain speed until like 3 seconds after which is not normal and I don’t know what’s causing it. I got an oil change and it still hasn’t helped and I don’t know what it could be. These problems started after getting admin tuned. Anyone know what could be wrong?

 

how often do you change oil ?

 

What does admin tuning say?
are there any codes?
heat problems?
What do the data logs show 20 mins in?
NA or boosted?
manual or auto?

I'm not sure how high oil temps would cause the car to run sluggish as limp mode is alot more obvious: https://www.myg37.com/forums/engine-...limp-mode.html

What are the air intake temps (this and mass airflow are available via an OBDII reader)? Wouldn't heat soak through many of the aftermarket chromed intakes cause this type of behavior since much of the country is in 100+ degree territory?
