Another thing I'm thinking about changing is where the venturi tube for my Tiptronic trans connects into the pipping. Right now it connects into the pipping after the MAF sensor. So it's pulling air out of the system that the MAF sensor did not account for.

So I'm thinking about moving that connection to the air box before the MAF sensor. What do you think about that?

Move it to here? This would also allow me to use larger pipping and not worry about putting that connection into it.

logging it of course is best. You want the open loop numbers, that is when all the sensors are doing their thing and you are at WOT wide open throttle. The closed loop stuff will fluctuate but always kinda read like what you have gotten already. Closed loop is just cruising or idling. You want your open loop numbers to be around 13:1 for best performance. (disclaimer) I was advised this by somebody but please have your car tuned by a professional for safety of the motor and performance. Pedro can probably help or FVD. Giac if you can get them to get you on their dyno. I use a wideband 02 sensor.

Ok, so I'll get my daughter to ride with me, lay the hammer down and have her log the info. She got to ride in it for the first time this morning. I have the speed gong set at 70, so I know to slow down to keep the spoiler from deploying. She heard the ding at said " we hit 70 already?" lol.
