You guys are doing great and even if it seems slow to you I can't believe how much you have accomplished over the last couple months.
I would consider moving your air/fuel sensor up the pipe a little unless it has been working fine for you there. At low rpms and maybe at high rpms depending on the cam you could get reversion up the pipe that could effect the readings. Ours is up about where I put the arrow and we still get some false readings from O2 being sucked up the pipe at lower rpms.
The other thing is I can't remember for sure what the operating temp for these is, but I've added a copper wing type heat sink between the sensor and pipe. I looked for a picture, but can't find one. I think I made it to the specs on Innovates site ( http://www.innovatemotorsports.com/
Here is what they say:
The maximum temperature of the sensor at the bung (the sensor hexagon)
should not exceed 500 oC or 900 oF. If these temperatures are exceeded in your
application you should either install a copper heat sink (instructions below) or the
Innovate Motorsports Heat-Sink Bung extender (HBX-1).
The bung extender is recommended for situations where airflow is restricted or
the encountered heat is higher than a heat sink can handle.
They show how to build a heat sink here on page 8 and that is what I used:http://www.innovatemotorsports.com/support/manual/LC-1_Manual.pdf
I got the copper from Greg at Motor Sports Innovation (609) 265-2110. If anyone is interested in getting Innovate's wide band air/fuel controller and sensors give Greg a call. He has us LSR guys in mind.
Maybe none of this is a concern for you guys, but just though I would throw it out there,
