I test drove a 2007 with an Edelbrock EForce 600 HP Kit #1594 and Innovators West 8 Rib Pulley system 10% Overdrive set up among other upgrades. Got on it and boost got to 10 psi and then something broke and car shut off. Opened the hood and it was the idler that broke and ripped the wires out of the throttle body connector. The car has a dyno sheet showing 556 RWHP. They said they will fix it of course and I will test drive it again. Is this a part that should be upgraded or is this a sign there is something else is wrong?

There is an upgraded tensioner from Edelbrock to replace that. It comes on the kits after a certain date and was a free replacement on the older ones.
