It looks to me that at 150 g/s the air is moving around 24 m/s through each bipipe.  18" of extra travel equates to 0.02 extra seconds.  At 200 g/s about 0.015 seconds extra contact time.  I wonder if the extra time really matters.

The outside temps here in Florida been low. I got some logs when it was 70* degree's out.

Seeing some good results. Same tune as before thats posted. 50/50 mix of w/m dual 225 ml/m nozzles and 93oct. Logs attached below, one log I thought car downshifted out of 3rd so you'll see TPS go 100 then drop and back to 100 this screwed with results a little. The full solid 3rd gear run was done good. Car runs alot smoother on w/m and had to add in check valve and throttle response came back.

**Side note question, how do you setup me7logger to output seperate files each logging session? Mine keep going into the same file and add in a few rows down.***
