Can i do this with just a vacuum gauge to start with ?

This is by design.

Regulations vary by country, but Europe and Australia require speedos to be accurate to +10% plus 4km/h but never below actual speed. US has a similar, but more complex standard that covers the allowed range. To comply with the regulations, they typically indicate 1%-2% high.

is the odometer effected too?

It's a driving technique. You can do any of them regardless of gauges. The gauges just help you determine how effective they are in real time.

You can still see what the effect is when you fill up the tank.

From what I've seen, odometers are much more accurate.

on the way in this morning, i remembered to try and test the accuracy of my odometer against the sign posts on the freeway. i was only able to get 2 miles in before my offramp, so its a really small sample size. but my odometer clicked over to 2 miles several hundred feet ahead of the marker. i need to get a larger sample size to determine more.

as far as the instrumentation, i think the vacuum gauge is going to have to be first on my list due to price.

Do you have a smart phone?

The Torque app and a Bluetooth OBDII adapter is another cheap option. I don't have a smart phone, so it doesn't work for me. But if you do, you can get this for about the same price as your vacuum gauge.

I've got an iPhone, and there is no torque app. there are several other similar apps, but i dont yet know which one would be appropriate. it also would have to be a wifi adapter as bluetooth wouldnt work with iPhone. with that being said, it may be worth it just to pick up a used android phone or tablet for a dedicated one. also, there are not a lot of good places to stick them in my car without just setting them on top of the dash which i am not super excited to do just yet.
