this night in highway i drive a little trip whith my evo 9 when i come 5 gear in 230 km car jump from road maybe 1 seconds then car came lean.when i push throotle in 7000 rpms afr comes 17 and car stop. i check oil lever okey coolant level okey i take boost 1.2 bar car make the same thing again.also i look all hoses blow off and intake manifold everything is alright what can be the problem.maybe fuel pump take a bad shock when i jump from road is it possible.

 

check with your mechanic & tuner make sure your fuel pressure is holding while engine is running

 

So, let's recap:

You were running in 5th gear and all 4 wheels left the ground and now whenever you are at 7000 RPM and boosting, your AFR leans out and the engine dies?

I'd agree that the first thing to check would be the fuel pressure.

How are the AFRs while cruising and idle?
