Tune- normal driving mode vs comp mode
My car is professionally road tuned. It's an 03 base with full exhaust and a vararam intake. It drives great on normal driving mode but if I switch to competitive driving mode or traction control off mode it seems as though the tune is no longer applied. When I change modes, the instant throttle response is completely gone and the car is just lethargic. When switched back to normal mode it's great again.
Does anyone know what this is all about?

There are only a couple tables in the tune that deal with traction control when it’s on.
They are timing tables.
I can’t imagine how turning TC off would have anything to do with the tune. At all.
So something else going on. Maybe it’s applying the brakes somehow.

I had suspected it would be something along these lines, and was hoping someone would know what it really was. Thank you.

Interesting, so these cars can have slightly different tunes depending on driving mode? Wonder if they can be used for fuel type or activating nitrous.
Normal setting with sleeper tune and kill mode in competition would be nice.

Are you talking about competition mode on the traction control button where you hold it down for 5 seconds?

Would you happen to know if theres different tune tables in sport, touring, normal or whatever the 3 dial switch is. I thought it was just for the shock stiffness on f45 equipped vehicles and doesnt alter the pcm just the shock compression? Mine is a 99 but they dont adjust as i have regular 97-13 new base c5 c6 shocks without the sensor valve option.

I don't think my 99 has comp mode. I tried holding the switch 5 seconds just either traction control on/off.

All three of my 99s had it. Your car needs to have the active handling option code JL4. It came out as an option in 1998-1/2 models.
You need to be at a full stop in order for it to engage pre 2001. The 01's plus you can engage Competive Driving on the move.
Pressing the active handling button once (at any time, even if car is in motion) disables traction control and stability control. Holding the active handling button down at a full stop you will see "Competitive Driving" come up on the DIC. Which disables only traction control but keeps stability control engaged.
It has nothing to do with the F45 or F55 adjustable suspensions..
