Speedometer off by 5mph

I have a 2011 Tacoma TRD with a 3 inch lift on it and 285/70r17. Since I've done this my speedometer has been off by 5mph if it shows I'm doing 55mph im actually doing 60mph. Any tuners/programmers out there that could fix this so I don't get anymore tickets

 

It’s more like 5 at 50, 4 at 40, 3 at 30.

 

This is good. If you get pulled over just tell the cop that your guage showed a slower speed

 

Thats what I told them but when the speed limit is 60 and im doing 67 they have me on radar at 70 to 75

 

Yeah if you go to any 4wd store online or offline they should have them. They're pretty expensive though ~$250 but pretty much the easiest option

 

Hypertech makes a handheld unit. About $200 I believe.

 

The hypertech works, I used it to correct my speedo for my 285/75r17 tires. Hit up @eccracer104 and see if he can hook you up with a slight discount from the normal $200 pricetag.

 

Sometimes they work. Ordered one for my truck, and it didn't work. I could connect to it and program it, but the speedo/odo didn't work after install. After Hypertech's CS hung up on me, I uninstalled it and returned it to AutoAnything for a refund.

Ordered a Dakota Digital unit to tryout for half the price of the Hypertech. I'll install it once I get my truck out of the shop.

 

HP Tuner can also adjust the speedometer to match the tire size. Rabbit hole though.
