Don't have them I only have the power level of the WHEEL hp at 436.6 and the FLY at 488.9 don't have the graphs at min as at work till Friday

 

That 436.6 is that on a hub dyno?

 

Because I believe everyone hear is talking about power figures at the flywheel not 440bhp or even 400bhp on 440cc injectors at the hubs. As I would believe your engine isn't getting enough fuel by the sounds of it

I am getting 436 rwhp this is safe I am running 10.0 on aem Afr.

 

You can get the power from then as my dyno sheet proves. No doubt I'm close to maxing them out but the power is possible and SAFE

I'm starting to get the feeling that because one person said the rest take it for gospel.

On a 6 cylinder petrol turbo a rule of thumb is the cc / min of one injector is about the most BHP at the flywheel you can get out of well mapped engine before running out of safe injector headroom. People push this margin, or kid themselves they have 600 BHP on 440 injectors, but it's a tried and tested guide.
