Do you have headers? I sort of want to assume you do based on the fact you are pushing 390whp. If you don't, that might explain the peak being in the low 6,000 rpm range. However, it hardly looks like it drops off much from there on up.

Did they try to pull RPM with one of those induction clips over a plug wire? If so, I wonder if they couldn't account for the fact that it uses waste spark? A lot of GM (and other) cars are like that, but maybe not the kind that frequent dynos (I think the ZR-1 might be the only Corvette that used that type of ignition). I know the emissions shop I take my 'vette to seems to have a real problem with it.
