Your car has 4.10 gears right? I have heard that cars with gears will dyno lower than cars with factory gears.

Actually it has 4.33's. I've posted your question before and never got any type of definitive answer. I wish it were true but can't say, no one on the forums has been able to tell me if geared cars run lower dyno numbers compared to stock gearing. If you know of any info on that let me know.:mrgreen:
