ill get back to tomorrow on the stock numbers. stock sti heads, 7200 is rev max set on hydra. the dip your seeing at end is because we are maxing out injectors at 25psi.

That dyno chart is hard to read.

Does it show that you are losing power from 5600 to 6300 and then making power again???
why would this happen?

Need to clean up timing, that dip can be reduced with a nicer curve.

They indicate it is due to fuel but it makes no sense.

The fuel system was capable of making 570 hp at 5600 but only ~500 hp at 6000... Most tunes I see have the same AFR at 5500 as 7000 rpms. Unless they decided to run a good bit richer above 5500 the dip has to be something else...

assuming that your boost isnt falling off the planet up top it would seem your car should be able to take a crap load more timing.....that 100hp fall off is weird.

A gt35 should be making peak hp close to redline on a 2.35 litre.
