Mine won't really smoke em either like i think it should.
Manual Mode
T/C and Stabilitrak off
On good dry pavement
Must hold breaks and wait for both tires to spin
Once spinning start to let off brakes
Then spinning quickly peters out and my engine lags for a bit then it goes... kinda
I've done a fuse pull which helped but still not like I expect.
I can BARELY spin tires in a turn while in 1st or 2nd at 3.5k-4.5k rpms
Suggestions?
