I just picked up a Chip from James Duff with computer. thy don't list any install instructions on there site.
I am running my timing 12 TDC, so I was wondering do I need to set it back to 10?
anything else I might need to do?
 
generally i start at 10 and go till it pings under crusie load and go back 1-2 from there.
 
Thanks for the info, I installed the chip and no ping with 12tdc.
not as big as a increase as I hoped, but it seems to be alot smooth power in all the RPMs.
not a bad 25$ find off of CL.
