So what are you trying to say?,there are 100's of reasons that there is a power difference dont just blame the Hondata because that is the only difference,what about valve clearence,and every other mechanical or electrical part in the car that controls the output of the engine.Maybe his tires had less tire pressure or his wheel alignment thats plays a MAJOR roll in FWD power figures.I am so sick of hearing I make more power on this dyno and my mates car has more work done and he makes less power but when we race he is faster than me.A dyno is a FU**ING tuning tool but unfortunatly with the internet they have become harder to use as a tool as everyone wants to know why there car makes more power than there mates with less mods.What is the difference when you race each other on the street and not from a standing start.

Dyno Dave,

I dont think he was trying to blame Hondata for the numbers, rather asking why there is a difference between the numbers being produced.

I think you started answering that at the beginning of your post and I would like to here of more reasons or explanations as to why this is happening not where to place blame.

No problems ;).

So other than say a bad or improper tune and how the car was run in, what other factors could cause such an equality of 'power levels' with such different mods?

With some of the cars turning up with semi slicks I have seen as much as a 10kw lose in power it can be that simple.
