Why whp so low? is that normal?

 

use sae carrection factor

 

Tunner from shop said he didnt add any correction,so number seems lower, but in fact actual whp is as same as the one by adding the correction.
Is that possible?

 

Yea don't use correction factor. BS for a turbo car.

Do you have the log you used for this? That would tell us more.

 

hmm no, since i dont have cobb, so no data saved.
Some of my friend changed intake and the entire exhaust as same as me, but their whp was around 320 after tune.
Mine are so low, that is my concern.
Tunner said, he didnt add any corrections, therefore the number was low, but the real whp suppose similar as my friend's evo,
This tuner try to told me, the correction always give exaggerated number on graph, but that is not real. If he add some corrections during the tune, the number would be over 300whp.
is that possible?

You have a log, that is how that dyno chart was made, it's not a real dyno, it's taking it from a data log. Who logged the car? If it was your tuner, ask for the log file.

 

If the car has a stock boost controller, that may be about right..
