When the tuner raised the rev limit to 8.5k some more horses came into play. We are now at 298whp.
Apparently there is around 25hp drive train loss according to the dyno. According to the tuner his dyno is quite conservative, it's more negative that optimistic. So these are real numbers.

What’s the ratio number reference at the top? 4.813? What gear were the runs done in?

That top graph showing 335.9HP, is more per litre than my 360 Modena.

I'm hoping its not a diff ratio so there's a multiplier in the software calcs
Thats 3ltr

Yeah, it's a stage 4 engine which seem to produce some heat
Joke aside, the tuner did install a air inlet temp tensor so the ECU can compensate for bad conditions. He also installed a oil and temp sensor for the ECU so the engine can shut off if it detects any problems

What is Robert? I’m on about the ratio type number?
Look at your post JASON

The dyno is an Inertia dyno. The ratio is there so the wheel size and size of the inertia roller matches 1:1

I have? I’m a little confused?
I only ask as I was once getting random figures from an engine and there was a number error in the software on the drive ratio that was altering correction factors
