I've got mine rough tuned for 11.6-11.8 at the torque peak (3950 rpm).

Screw the warranty..... just do the cams.

You can run over 30psi on the stock injectors - that has nothing to do with how much boost you run on the stock turbo. What matters is octane - you need higher octane to run 26psi, and you don't need to upgrade the injectors to do that. Slap your friend in the face next time you see him for trying to get you to buy those injectors - lame.

You need a proper tuner and proper fuel to run higher boost. 23 should be fine on pump gas with the fuel pump and a good tune.

I think this is pretty accurate, besides 30psi on stock injectors, this should be assumed for the stock turbo perhaps. Your fuel support is going to be dictated by how much power you are going to make.

Yes, stock turbo only. At 30psi, you'd want to be watching IDCs, but by no means does anyone need injectors that are 2 sizes larger just to run 26psi on a IX.

Injectors are not needed.

You should not exceed 24psi on a 2003-2005 Evo 8 on stock turbo. Use ignition advance if there is more room if air fuel ratios are optimized and boost is set.

2006 IX still see gains in the 26psi range.

ok thanks for the advice so far.... anything else to consider or any more advice to be given?
