I modified the rom code directly much like a tephra mod to accept the mivec tables as a gear dependent switch instead ..
I also modifed a bunch of other stuffs ..but nothing like tephra's fancy rom .. and I only do it on JDM roms .. so usually I have to convert to a USDM rom ..
The worry is always brickin the ECU if the codes are wrong ..

This is because its not a table that can be easily changed ..

Well, maybe you can work with Tephra and verify the codes to all the rom ID's and this can be an optional purchased package to Tephra's rom...
Granted many will not pay alot, but those who need this will most likely be willing to pay a fair price to have great spool on a large turbo.

Same sort of surging happened to me with the 64mm cover on my HTA Green. You need to spend the 200 dollars to upgrade to the 84mm flow advancement port and it will really help. I had terrible surging on my setup and switched to the 84mm port and the new Tial QR bov and there is now 0 surging whatsoever, it acts like a totally different car. I realize yours is an X, but the larger compressor cover should still really help.
