Cheers.
I can't even change my boost. it's programed in ecu and I have not entrance.

If you have a durametric log for any runs between 3k-5k RPMs (in 3rd 4th or 5th gears) showing LOAD, RPM and boost pressure you will know your exact torque numbers vs boost levels. You could email it to me if you would like and I can work it out.

You really cannot get close to those torque numbers at stock compression and 1.5 Bar of boost irrespective of turbos, intake, head mods and cams used.

BTW your HP numbers at 1.1 Bar are simply amazing!!

Help me out?

I always see dyno charts with HP and TQ curves crossing at 7119 rpm especially when the rev limiter is set at 6800 rpm.

TT Dude,

I am not sure what you are trying to get to or what you are finding so amusing or why are you diverting this thread, you asked a question above and I answered you. You do not seem to be familiar with Dyno readings in NM, they don't cross at 5252.. they cross at 7119 if anything. You might need to research this.

Check the dyno graph shared by Karol on this post above.. You might be able to see it.
