[Supras] MAFT

[Rockey Fox]

Most notable so far is no fuel cut at 11psi this morning during the long straight away pass in 56 degree ambient air.  Previously I was running 10 psi using the shimmed wastegate mod and would consistently hit fuel cut in this particular straight which is my favorite passing zone. I'm not sure whether it's the AFR being better controlled by the MAFT or the electronic boost control or most likely the combination that has accomplished this.
At idle I'm at ~ 14.5 AFR which seems normal although I didn't previously have a WB O2 sensor prior to this install to compare.

I no longer see a huge black cloud when I boost and the AFR is in the 11.x range at WOT which is adjustable in the MAFT-Pro. I'll have a much better idea of what's actually taking place pretty soon as my next step is to hook up Tuner Pro on the laptop so I can record logs while driving. 

Right now I'm getting the information while glancing at the LCD for sensor readings while driving. I've got the head unit Velcro'd in place right between the shifter and the radio. Since I've got an after market radio I have a nice cubby hole under it to stash the head unit when I'm not monitoring or adjusting and its out of direct sight which lessens the chance of being stolen while parked topless.

    Wonder if you are running a bit rich with "out of the box" settings, 
a characteristic of better idle, not to mention the check engine light.  
More importantly, have you noticed any performance improvement?  I 
realize you have not started tuning yet.
