What's that supposed to mean Andy? Are you saying that the process assumes greater gains from an IT tune on motors w/ larger displacement? [/b]
It is most certainly a consideration on the subjective side of things. Not part of the 'formula side, but always a consideration. (Not speaking specifically to the Fiero and it's weight, just pointing out that apples that look like apples may not be apples) IIRC, the ID 2.5 Fiero was one car that was 'left alone' in the great correction due to the lack of knowledge base, participatory drivers and large displacement (potential for atypical torque numbers in IT.
