Has anyone experienced their car losing power when you shift at a a high rpm? When I shift from 1-2 and 2-3 sometimes the care acts like the rev limiter is kicking in when I stomp on the throttle. Anyone experience that yet?


Oh and I dont have th track key programmed yet.
 
What octane gas are you using? Also, are there any additives in your tank? minimum 93 octane, no additives. You probably know this, so just asking.
 
im in Ca so I only get 91 unless I want to pay 8-10 buck a gallon for race fuel. Its only between shifts and no other time. Im thinking a flaw with the T/C
 
I'm on CA 91, I don't think I have that issue. Is it while you have the clutch depressed, or after you release after you shift? There is a rev limiter which you may be hitting if you are power shifting
 
Thats the TC doing its job.

If you don't think so then completely disable TC and let us know what happens.

It's traction control.

At full or nearly full throttle shifting at high RPM these cars will spin the tires hard going into second and get a good bark going into third, if you have TC turned off.
