Taking a closer look, I think your injectors and/or our fuel pump are maxed out from 4800rpm.
possibly, It might be fuel pump. Only have the single walbro when we did tune. Jay did say we could go more but car was already making more than safe limit for torque. Will double check with him though.
I'm very surprised it made that with the walbro 255. My car was out of pump, on pump gas, at 26.5psi of boost with a walbro 255 with the red.
I agree the fuel setup doesn't look like it could support the power this Evo is making. Were ambient temps different? Maybe it was done on a road with a slight decline? Was your Evo 8 road tuned like this Evo 9? Maybe the MIVEC gave this Evo an advantage?
The 93 tune is pretty healthy but it doesn't surprise me that he made that much on Sunoco 104, it's got higher octane than pump E85 and doesn't carry the lower energy density downside that ethanol does. Keep in mind he is on an SS housing and that will give him more top end power.
Also there is no CF stated on the dyno sheets so it may be different than what most use.

Temps was probably close to 90. Also logs were done on the same road in both directions to make sure it was accurate as possible. Car does feel amazing though!

What does CF stand for on the dyno sheet? Still new to all of this. But yeah the SS housing is amazing on Sunoco 104. Like I said before we could have went with more boost but decided to leave it there because of the torque already exceeding the safe limit.

On dynos, there is a CF (correction Factor) for air temperature and elevation correction to estimate at standard temperature at sea level. I haven't heard aboutva CF on virtual dyno. Althought we set entire car weight with passengers to estimate the whp and torque.
