[QUOTE="bigbirdwpg, post: 14734315, member: 170150"] I bought the car new, (2012 GT/CS). I monitored AFR, fuel pressure and boost, was always ok. When it started pinging at WOT I was never able to stay on it long enough to see what the af was doing but at less than full throttle is looked good. I had the car dynoed shortly after install - was pronounced good, conservative (498 RWHP). It checked out at 9# boost max just as advertised. The motor had about 30K miles when installed. I now need a new engine. So my engine lasted 6 months - less than 5000 miles. I am not doing a tear down - but the dealership says there is one damaged piston with oil on the plug, fails the leak down and compression test. They recommend a complete rebuild or replacement. I am installing a new coyote with 3 year warranty and putting the edelbrock up for sale. [/QUOTE]
