I think what gear the sample is from would be good info as well

1. IX Ported turbo
2. Stock Evo 8 block 4G63
3. Fuel: 100
4. I can't remember, it was a NASA time trials car
5. 24psi straight across to 8k
6. ECU-Boost using GM 3 port solenoid
7. Ported Titek

3rd gear:



4th gear:



- Bryan

 

That is an amazing boost curve. Do you attribute the ability to hold 24psi to the GM 3 port? Would be terrific if you could hold say 28 all the way across tapering down to 26 or 24 psi closer to 7500 rpm.
