My car is dyno tuned with Osiris. I just got around to changing my valve covers and they were leaking much more than expected. A plug on each side was nearly drowning. While I was in there I put on the copper iso thermal throttle body heater and aramid gasket. So now there's basically a small throttle body spacer installed. I am completing the job tonite so I haven't driven the car yet. Do you think my tune will be affected enough to warrant getting it corrected?

 

Doubtful... the change is so small (intake temps only basically) the ECU should have no problem adjusting to it. Just be sure to reset the ECU afterwards... since you should be disconnecting your battery anyways then you're probably good with that.

 

Ok thanks. That's what I wanted to hear. My battery has been disconnected for 2 days so it should def reset.
