Was at the drag strip friday running strong. Traction control button off. Running a stock 265/55/20 tire up front and a 305/45/18 mt et street radial in the back so brake light and abs lights were on. But dont know if it had something to do with the 2 tires sizes but as soon as it went to shift into 3rd at 95mph, my traction control light started flashing and my truck shut down. When i have the stock 20s on all four corners i dont have any problems at all Anyone got any ideas?

 

you need to pull your ABS fuse and you will be good!

 

Yup pull the fuse

 

I bet your problem is due to being tuned for your stock 20's. When you changed to the18's the mph your truck is set to shift at changes with tire height.

That's my educated guess.

 

Thanks guy ill try the abs fuse on the 6th of jan when i go back to the track. Dont think its the tune because when i ran stock 17s all around on same tune there were no problems.

 

even with traction control and stabilitrac turned off, it still knows your back tires are spinning faster than the front and causes that crap to happen. I had 275/55R20 in the front and 28" DRs in the rear. Pulled the fuse and everything was good!

 

This is awesome to know!!!

 

Hey guys looked in the manual and got 2 abs fuses. Under hood #9 small fuse and #61 big square fuse. Pull both or just 1?

 

it's fuse #9
