My Dinan Stage 2 track results have multiple 12.5s@112mph runs with a race weight of 4760lbs. I also easily beat the lighter 500hp SMG equipped E60 M5 at the track. I've clocked sub 4 sec 0-60mph runs. So, I'm pretty sure Dinan provides way more than 17hp. Anyway, if one doesn't like a Dinan product, I believe they have a 30 day return policy. Although, I'm not sure who pays the dealer labor on a refund.
