Speed limiter?

[Wigjiggy]

Does the Z34 have a speed limiter? I’m at Daytona this weekend, and every time I hit 140mph, the power kicks down. Not limp mode, just a quick bump that stops my acceleration. Oil and water temps seem okay. Thank you.

Yep. If you been tuned. They should have reset it higher. Mine is reset to 199. Plus the Z is aero limited to 155 with the stock horsepower. If you added aero downforce to the Z. It drops a bit lower because of the increased drag.

Thanks Rusty. That’s what I suspected. Now I have an excuse for my sucky times this weekend. My tuner must have missed it. I have front and rear aero, so I’m going to have him set it really high. At most tracks I run top speed is not an issue, but Daytona 24 hour is super fast on the NASCAR portion. Thanks again for the help.
