Holding more boost at redline
Hey everyone. I have an Evo IX with all the bolt-ons, ported exhaust mani, o2, hotside, etc. My car holds 28psi till about 6k and drops to 21.5psi at 7k. Anyways I can hold more boost by redline?

ecu boost
|
What are you using for a BCS?
|
3 port boost solenoid & crushed MR BOV would help.
|
I have ECU boost with crushed BOV. The WGDC is at 100 by 6k rpm.

The most my stock turbo ever held was 26 psi till redline and peak was 28..I had a blox mbc clone of the hallman and was better in terms of spool and the way it held when compared to the hallman funny thing was I paid $70 for it.

Yea. It,s preloaded. It won't go any more. Not sure what is going on then. |
Checked for any boost leaks?
Also, the tune can be a factor on how you hold boost. (not the boost tune) |

Even if you got more boost up there the power wouldnt increase from the heat. 22 to 23 at 7500 is about it for HP
