I just got some 285/70/17s tonight for my 15 Sport! Im so excited to get rid of the silly 225/75/16s... The way i understand it, I need to get something like the Procal/Flashcal to adjust for my TPMS, speedometer, and shifting points on my auto trans. How soon do I need to get something to flash my computer? Is it a ASAP or damage will occur, or do I have a couple weeks? Are there any other options? Who has the best deals?
Thanks

You should be fine until you can get one your not that much taller than stock. your gas mileage will suffer a bit but should be ok. I would just get the Procal since it's ready to go out of the box and everybody seems to have trouble downloading the spark program for the Superchips Flashcal. I've had both currently running the Superchips and if I had it to do over I would have just went with the Procal again as it's much more user friendly.
