I went to the track this weekend and on the second run my DIC started flashing something about my brakes and reduced engine power. I switched from my 31" street tires to the 28" DR's and I noticed my RPM's where at or near the 6000 Rev limit on that run. What could have caused the message and could it do any damage?

 

my truck does weird stuff like that at the track once in a while too. it all goes away quickly after leaving though.

 

I think it was my ABS being set off because I was spinning the rear tires and the fronts were not spinning as fast. Plus the spinning caused me to hit the rev limiter before the shift into 2nd. At least that is what I think might have happened. Would it slow me down because I managed a 13.9 on that run.

 

yes it's caused from the different tire sizes
