I would want to have an AFR Gauge. Doesnt have to be 100% accurate just consistent. By that I mean that if you are tuned to 12.0 AFR on the dyno and the gauge shows 11.5 AFR consistently their I would be fine. I would know if it got above 12.0 I had a problem (Actual AFR up above 12.5). Could save your motor.

Boost Gauge would also signal issues like a leak or unusual conditions (ie High boost caused by low air temps and high barometric pressure).

I would like to have both if it was my car but I feel the AFR is by far the most important.

you can adjust the settings in the Aeroforce gauge to tweak the AF ratio gauge's readings. so if you have a very accurate gauge to compare with or if you know without a doubt what AF ratio the tune is set at then you can tweak the readings yourself. just don't compare it with a tailpipe sniffer, sniffers always read lean compared to a sensor mounted up front.

dont need to be blown to get a ticket, got one last night... 55 in a 40... i want to get a blower but now this is gunna set me back.

anyways good luck man, post some numbers when ya get them. i was thinking vortech as well, but most sixxers have x-chargers, but the 0% for 12 months is very tempting...
