Finally a 928 owner and loving every second! The 1993 GTS was gotten from Wilhoit Ent. and is everything that I expected it to be. My question is whether or not there is a performance chip upgrade available, if it's worthwhile, and if so, will increased engine performance compromise anything else like the transmission etc... THANK YOU all for the info I'd gotten in the past. This is a dream come true. I attempted a search but being computer illiterate to a degree, did not find anything easily.

 

Read this thread to see what's coming in the near future.
