I've been using one with Torque Pro in my Civic Si (and hooked it up to my PT before buying it to look for error codes) for five years now. They are very accurate.

HP and TQ are calculated so expect those to be off, but consistently off.. so you should be able to tell if upgrades help or hurt.

reading sensors.. those will be as accurate as the sensors.

i can adjust BSFC and the weight of my mustang in my program and make my laptop read anything from 2 to 2000 HP... meaning you're at the mercy of the programming unless those are things you can dial in.

when you put it in 2nd and floor it to redline do you get a realistic max HP and TQ? should give you an idea of its accuracy. what PT do you have? a 2.0 euro model should have 140hp and 130tq in perfect condition at the crank so i would expect you to see no more than 110/110 for a "to the tire" reading if it was 100% accurate (:

i'm interested to know how accurate it is as well..

looking it up, i see:

150 @ 5,100 rpm Horsepower
165 @ 4,000 rpm Torque

if you're one to try it out and let us know what you get, i'm curious

-just dont get in trouble on my account

you can compare it to this to see if it's in the ballpark(rear wheel power shown): https://www.knfilters.com/dynocharts/57-1550_dyno.pdf
