So for a no cat exhaust, what's the safe AFR range? I'm seeing 9s, 10s, and 11s.

I dip into the 9s when I come off the gas after a hard push. 11.5ish when I'm in it hard. 12s when I'm halfway in.

Which pulley does it have? Meh. Doesn't matter. Get a smaller one already!

2.825" URD. Doubt I can go smaller without a 7th, bigger injectors, and or more tuning. Only have a MAF Cal (which isn't installed or tuned yet). And there's close to zero chance I'm pulling that damn blower off anytime soon. Also she's still my daily. Can't go blowing it up. Oh have I ever said I hate coolant?

It's no fun until you blow it up!!!!

Agreed, but I couldn't be happier to finally get it done.

Not sure if this helps, I see 10.25 WOT and 14.7 cruising.

It's the Ucon and not the TRD reflash though.

Thanks for the info, I'll get it dialed in over the next couple months. I think if anything I'm running a little rich so I'm not all that concerned.

What are TRD guys using to monitor the coolant in the supercharger system? Or just to monitor the blower in general. I'm going to have room for 2 more gauges here shortly. I was thinking oil pressure/temperature, and water temp or exhaust gas temp. I'm already running boost and AFR.

Oil pressure is a very very good gauge to have. Trust me. ;)

Ya, that one is a definite. What about trying to monitor the supercharger in some way. EGT would tell me if combustion gets too hot, but would water temperature of the low temp radiator for the supercharger be better?

Oil pressure is gold.

Intercooler temp sounds interesting, but I think an E.G.T. would be more useful between the two. Fuel pressure might be another one to consider.

Unfortunately Innovate doesn't have a FPR guage in their MTX series.....

Skip EGT. Old school, not really accurate or useful. Wideband AFR is the way to go.
