Allright I finally got my 265's slapped on and have one question. The service manager stated that reprogramming the TCM or ECM was only for adjusting the ABS brakes. He tried calling VCI to ask but they closed at 5pm. I thought when they went in with tech II to adjust for bigger tires It changed everything in relation to the tires(ie speedo, odometer, abs) Was he correct or was I correct. He stated that when he went in with Tech II it would just affect the ABS, not the Allison shift points etc. Thanks In Advance Bill
PS. the 265's fill up the wheelwells very nicely

Your dealer is correct.
