hi guys , i have searched for ages for this but could find anything, i have a s7 fd and just wanted to know if you can retain the thermowax for cold starts if the emissions gear has been removed and the twin turbos have been converted to non seq. or is removing the thermowax (and corresponding coolant vaccum lines) part of the emissions removal or the non seqential conv. any imfo is much appreciated.

 

Should not be any reason to remove the coolant lines going to the thermowax. As you noted it will help while car is cold.
