Dans Turbo Build

Sorry, no hump either!

If it's not the vvt then I guess it must be something to do with the pipework that's different on mine.... Maybe

I haven't got that dip on mine... Is your standalone ECU controlling the vvt?

Hump not dip. Lol.
Yes. I believe he's doing voodoo stuff with it.

Hmm. Odd. It's no issue at all. Greg just thought it seemed engine related and wanted to check his theory.
And then got curious with the 2zz.

Yours must be special monsi. Just did a random search and every single 1zz dyno chart I can find (within reasonable builds, not silly idiot power) all have the hump. Some more pronounced than others.

I haven't got any pictures/graphs. Day got to be very long and I forgot to ask before I left. They are stored on the system though. Will pick them up next time!!

I mean...did it even happen?

My bank account is empty so I presume I didn't dream it

[monsi]

That's why I think it might be down to the layout/pipework as so far I haven't seen anyone with the same setup as me

@BahnStormer

The beauty of Greg's tuning was he didn't look at the peak power untill he had mapped a perfect linear curve (if there is such a thing)

I know what you mean - smooth curve

@BahnStormer

He was most pleased with the distance he put between my first run curve and my final run curve between 3000rpm and 6000rpm. I think this is what you are talking about "under the curve"

Similar, but not quite: that comment would apply to the mid-range increase, but that description is used more in relation to completely different shaped torque curves, e.g. comparing a 2ZZ that makes 200whp and a turbo that makes 200whp: if you were to draw the two power curves and see how many square centres you needed to fill in the area, the area under the turbo's power curve would be much higher since. Another way of describing it is when they quote peak torque on engines (especially TDI's), they often quote the range that it makes that torque.

Skip to 15min 45sec on this video and you'll see the sort of power curve you don't want, unless you "just want a number for your forum signature" (their words, not mine)
