Stage II
I had stage II installed when I took delivery with zero miles. Engineering at Dinan said it wouldn't be an issue. I believe it was released on March 19.
I'm happy with it.
Scott from Dinan sent me the following info:
Peak HP
501 HP @ 5000 RPM
Peak Torque
580 FT-LBS @ 3500 RPM
Stage 2 software is $3499.00
Stage 2 only makes a small increase in terms of peak horsepower and torque over Stage 1. The big difference is the amount of boost we are able to apply on the Stage 2 version in first and second gears.* The Stage 2 software will provide substantially faster acceleration from a dead stop and lower rpm.* Stage 1 is great, but Stage 2 is noticeably faster.
