Is the edelbrock-supplied tune on the car? Or is it some hack job?
If the tune sucks as bad as it sounds like it does - I wouldn't do anything (especially WOT or heavy throttle) until it goes on the dyno for a tune.
If the dyno tuner is good, you won't need to do any further adjustments and you can save yourself the $350 for the software. It is not easy to tune these cars and the VCT, thats why there are very few nationally known tuners for them like Bama, Brenspeed, VMP, Lund.
