Re: need help with '165 in Vette

On other then the 32 series of IDs?.
Have you tinkered much with the 32 vs 6E?.
The couple I've dun, were always a limited do it and run, but the 6Es just

   On the 32 there are at least 3 versions, and I heard of a 4th.  Think
it's a matter of geting the right starting bin..   Might ask Tunercat about
that.
