i've been running 33's for quite some time with no speedo correction yet and can say no problems here and i have never heard of any concerning this matter
anyway if WOL says "no" then dont worry....just get the hypertech to correct the speedo.

When your speedo shows 60 mph, you're probably going closer to 62. So if you keep track of your gas mileage, add 2 or 3 miles for every 100 miles on your odometer.
An unintentional benefit is that that you will get a several hundred miles of extra warranty on your jeep. When your odometer shows 36,000 miles, you will actually have closer to 36,700 miles if you don't correct the speedo.
