I'm in need of more help with my r33 gtst
It's running stage one but not the power to match
Pull away is kinda ok
But 50 onwards is pants.Drop a gear and its all noise and no pull
Any ideas where I should be looking?

If you've done a speed density conversion on the ECU then you will have to check for boost leaks mechanically. MAF-based load measurement it will be extremely obvious if you have a boost leak as the fuel trims will be massive. If you have open loop only on a MAF system then you will see the engine run much richer than what the ECU map would suggest.

The thing with answering these seemingly simple questions is that is so difficult to diagnose something via an Internet forum.
1. Make sure clutch isn’t slipping (revs don’t go up with no extra movement)
2. Check boost levels
3. Check fueling
