I will tell you one thing, when that pin drops down with boost it means buisness.

 

I'm running a DennyT stage II pin and it is deeper cut than even the M5 shown above. I still get 19+ MPG - with a little right foot care - in mixed daily driving. In pure highway driving at a steady 65mph I see 22mpg+. I'm not sure what the M series pins cost but DennyT pins are very reasonable. When I want speed the DennyT pin will put some serious speed down RIGHT NOW.

I'm running a DennyT Stage II right now. It fuels hard, and it is cut to teh same depth as the M5.

My DennyT is awesome, just fuels to hard down low. Oh and teh prices are the same.
