Tire size question

[duramax07tmd]

What are you guys plugging in the predator to get the tire size correct. I got 285-75-16 and i will plug that in and its still a little off according to my gps.

Just wanted to see what everyone else is using for their 285-75-16.

Thanks.

Has Diablosport figured out how to adjust for bigger tires and rims yet. Everything I hear this in not yet possible with the new body style GMC/Chevy LMM 08. Any comment from Diablosport??? I'm shopping for programmers and this feature is important to me.

Thanks
John

We have not had any issues adjjsting tire size inthe new trucks.

Thanks, Do you need to have gauges when using the predator? Does the programmer leave any mapping in the system when you take it to the dealer and do you have to take out the fuses each and every time you make a change.

Thanks

No need for gauges unless you want to play around with the high power tunes.

If you go to the dealer, be sure to restore the stock tune to the truck and they will have no clue you ever tuned it.

Pulling fuses is not needed as long as you make sure everything in the truck is turned off when flashing.

I started off using 270 75R16, but as the tire got worn down I had to start using 265 76R16. This was adjusted using my GPS.
