Do you need to replace air sensor or other mods to run the 1.3? Or replace air sensor only for the 1.1 flash? Just bought a spare pcm with 1.3 on it but no instructions to run it.
Thanks,

My air sensors were not removed. The location for the mounting of the sensor itself was moved to make up for the redirected air. It is supposed to read out side combustion air temps

300XS DBR
Here is my experience with the DBR kit on my 300XS.
Topend is 1-2 so far on my big number wheels. To me, it was very noticeable. My boat would struggle to hit 100 on most days and if I hit a really good day it would run 101/102. It runs that easily now. Not to mention the midrange acceleration is much stronger. I have data logged 6 different props on it to date and have 100's of passes data logged. So I have a lot of before and after numbers. All improved. Not to mention no rev-limiter so some props jumped 4-5 mph (specifically 26p) if I was on the limiter. None of those props are my big number wheels.
