40% drivetrain loss help needed
Hi all,
I just installed a phase 2 roush supercharger on my 2016 f150 xlt crew cap (4wd). I tried it on couple of local dynos and I’m have around 40% drivetrain loss. The costume tuning had a slight increase in rwhp over the roush calibration (391 rwhp) but still no where near the expected results. Could anyone please point me toward what might be the reason behind the big loss? And what can I do to retrieve some of the lost hp?
Mods:
Jba headers + catback borla atak
Fox 2.5 shocks
17” method wheels wrapped in 285/70/17 BFs all terrain

Not really they were around 25-30 psi. These are the result of two different dynos using the roush calibration. Unfortunately didn’t take a pic of the one using cutom tuning (I was regretting the choices I’ve made through my life🧐 buf it was at 391 rwhp
