GIAC chip

[CRG53]

Hi Steve.
There's a GIAC 93 octane RSA chip for sale on Rennlist, seller says it's made by Rennsport I.e. your shop. Would that chip work in a 1991 C2 with LWF, cat bypass and cup pipe.

Thanks in advance
Steen

Thanks Steve, out if curiosity, is there such a thing as a dual chip, I. E. Switch between say 91 and 93.
