Is it possible to adjust the speedo to be accurate with 33's?

If so how do you adjust it?

I subtract 4mph @ 70mph for 32's, or use my speedo app on phone

In my opinion I think you should try regearing to 4.88's thats the standard gear ratio for ring & pinion for 33's.Regearing should solve your problem. and it'll get you better mileage having the correct gearing for it too. You motor wont struggle as much with the bigger tires and youll see that you have better power especially whenbgoing up hills. People report a loss in torque as well if theyre not geared for the tire size. Here's another link. read into it. its on a jeep site, but same concept.
but definitely consider changing your gears.

So I have a 4 inch suspension and 33's with 4:10 i want 5:29 gears but what do I need to buy to do that. I plan to sas later that's why I want 5:29

If u plan to stay on 33's id go for 4.88's. 5.29's are for 35" tires.
At the moment I'm rockin some 31" tires with the stock 4.10 gears on my first gen 4Runner.
I'm also gonna SAS in about 3 months and I'm in the process of getting all the parts/kits and gears/lockers so when I start I know ill have everything ready to go.
I'm also gonna use 33" tires and I've already bought the gears for it. I bought two sets of 4.88 ring and pinions. One V6 for the rear axle and one 4cyl for the front axle because the axle is off an 1985 pickup. Both ring and pinion gears need to be 8" if you decide to SAS. If you plan to stay IFS then you need a 7.5" ring and pinion for your front axle and one 8" for the rear. You can NOT use ifs gears on a SFA. So make sure u get the right ones.

If you have a mechanical speedo, it requires changing the sensor/gauge gears.

If you have an electronic, they can tweak the circuit. (like the "yellow box" linked)

Check the yellow pages or such, a good transmission shop would know who to call also(if they don't do it in house).
