I was running 4.5-5 lbs of boost max. and the car was running very rich after my last recal work at Mazda with the R flash. With most of the better piggy back ECU's seemingly complicated for me and the stand alones being expensive, I spoke to the techs at Greddy and was told I should be able to get a manual boost controller for 2-3 lbs of boost with no problems. In addition, they said it should lean out more at top end. I had a TurboXS manual boost controller installed Friday and I have adjusted the boost to about 7.5 lbs and it does run much more lively and the a/f mixture has leaned out from about 10 to 11.5. The car does seem to run much smoother with minimal boost lag for a reasonable price.

 

ooooh. did you get the dual stage model??

It has a fricken top gun switch!!!

 

I have that TuroboXS 2 stage one on my other car. Right now its set for stock boost. I haven't wired up the 2nd stage yet, but so far its working good; no spikes. As cool as the switch is, I think I might hook it up to the switch for the ac for a more stealthy effect (no ac anyway).
