Is there a lot more boost control tables within the ecu that is not available to change through ecuflash? The reason i ask is that im currently using the 97250001 jdm 8 ralliart rom and with this flashed on the ecu i get nice boost control to 1.5bar with the stock solenoid but when i use a non ralliart rom like the stock rom or the recently patched tephra rom 96260009 even with all the tables copied into it the boost just doesnt feel the same, slightly unstable and tails off a lot more.

 

Anyone shed any light on this?

 

probably... maybe post up pictures of your boost tables from 97250001 vs 90550001
