Challange Chip 1995-355

geezz man did you not read my post that is 2 ahead of yours in the thread about this?

 

I got mine 3 years ago from Auto Sport Design in NY. They had one left over from one of their cars. I don't know that it was used in the racing series. but they developed it for one of their Challenge cars most lilkely after the series was over. I can tell you it made a difference throughout the rpm range. It did not effect may idle or emmissions. I had a chip from TAP previously which advertises in one of the Ferrari mags and it did nothing except raise my rev limit.

 

You know I wonder what would happen if we used one in our 348's...

 

Also sorry but there is no debate on whether the factory did a different chip for 355CH. If you would like to see pictures of my seal on my ECUs and the part no. let me know.
