Horsepower Reading on My Echo

[leasaunce]

Hi guys,

I have a stock 1.3L manual Echo that generates 86hp. I have been using the Scangauge II on it for 5+ months now and Since the day I got it, Max HP reading on the ScangaugeII was 86hp.

Yesterday After work, I wanna check IF there's a power gain or loss (since I haven't really pushed the car max out for several months now). I was shocked to see 99hp. So this morning I went out and tried again... (as some people told me, just an error probably) and this time it reads 106hp.

That's a clip of it, skip to about 15sec to the end. I just lost for word how it can go higher than 86hp (I'm using E10 Fuel, 10% Ethanol. I should've put the RPM reading too! DAMN IT)

Same time, same fuel, same engine temp? And same everything else that could affect it?

Either the instrument isn't that reliable or someone might have played a 1NZ-FE-swap practical joke on you.
