channels the airflow to the MAF tube or do you remove it? It seems like it would both help (channel airflow) and hurt (83mm smaller than I want to run) the airflow. NOt sure which is better. I'll be trying Buehn 85mm MAF for the time being.

Default *me* trolling or *YOU*??!! Where have you been??...

It was like almost 2 yrs ago that we did the Lemmi tweaking of the AMS software when Stage 2+...hehe.

I'm running the GIAC-x v.8 code and tweaking it. My system is flowing more air than I expected so my MAF readings with 83mm are high which seems to cause the ECU to dump too much fuel (AFR 10-11.5) despite me pulling -25% primary (max). I'm trying 85 this week.

Are you still Stage2+ with AMS?

Default Thanks. Does that internal tube mate up nicely with your MAF?...

there seems to be a gap between it and the Buehn MAF.

Default Yeah, mates up nicely. I was just talking about that internal tube in the RS4 airbox...

seems like it's a tad smaller (83mm diameter?) and there's a little gap between it and your MAF. Not sure if this will make a difference. Just thought I'd ask.
