What a retard.
Anyhow, consider hotwiring the stock FP just due to the turbos. I been out of the game but you might want to do the stock BCS trick to make sure the stock boost isn’t dropping off.
Also, TurboXS might be a bit weird on the let off due to the air coming out. Might want to consider a recirculating BOV. It does sound mean tho.
Good luck with it. Nice cars when cared for.
