Default HP Tuner Horsepower PID Help

Hi guys,

I am having trouble getting my horsepower to read properly...
Previously i added the horsepower rerading in my vcm scanner using rpm*torque/5252 but since adding my supercharger and changing to the 2 bar map it is reading WAY high, Before supercharger would read around 395Hp but now reads 780 odd, im not naive enough to believe it ACTUALLY has 780Hp lol
Does anyone know the matrh equation to fix this now its all been swapped or what i have to change?

Cheers guys

Jay...

It's all a rough swag and can be skewed easily. I wouldn't worry about trying to use it in those scanners. If you want a ballpark take your lb/min of air consumed and multiply by 10 and thats rough hp.

The HP PID is absolutely NOT a useful tool for anything. In the hands of somebody who could already do all of the relevant calculations for themselves, it could "in theory" have some use. For the people who might actually try to use it, it is pointless.
