Btw, there are also threads about Dinan giving people hard time when it comes to cover something under their warranty, just FYI. In any case, Dinan offers their own warranty and if you want the peace of mind, go with Dinan. Would I spend $2-3K+ for 20-30whp gain? Absolutely not!

I'm not interested in 20-30 hp....I'm looking for closer to 75 hp, but way more important is the smooth torque curve that extends 100 points higher 
480 hp and +500 tq in a rear wheel drive manual with room for wife and 2baby seats for $69k? Take my money!!! |
That's exactly what I'm saying! The gains that Dinan claims always at the crank and do not usually translate into real world gains. With just a flash tune that cost $600-800 you can get close to +100whp/+100lb-ft. The net HP/torque gain at the wheel by a Dinan piggyback will be minimal and not worth several thousands of dollars IMO despite the warranty. But don't believe me, get the Dinan and please share your before & after dyno runs.
