Hi Al. Sorry about that 205 non-sale. The guy told me it was for sale then changed his mind.
As for tuning a 205 I say stick with the injection. Carbs give you other problems that cost money to fix and with a well set up injection system there is not going to be a lot of difference but better driveability. The standard cam is the best one too. The 205gtidrivers.com forum is the best one for info.
