Alright, I am running an Injen CAI and a full header back exhaust with no cats. The car seems to idle at 14.7 and casually drive between 14.8 and 15.1. At WOT it richens up to around a 12.9-13.2. I was told that is actually a bit lean for WOT and wanted to get some opinions before I spray it, hopefully some time this week if things go well.

Also, would an EGT gauge be recommended for a 50 or 75 shot? I know that a sudden drop in EGT represents detonation, but would it be likely on a shot that small?

 

For boost, yes, too lean. For all motor your right were you need to be. With a wet shot it should be ok, just make sure you continually monitor. your idle and regualr driving is perfect.

You dont need an EGT gauge.

 

Awesome, thanks a bunch!

 

And I just remembered, he IS boosted... Thanks, again!

 

EGT gauge can not really measure detonation although never a bad idea just to be on the safe side. To do it properly you need a way to see the voltage on the knock sensor and log it or of course a good ear. Even a good ear can sometimes not hear faint detonation so I prefer to log the knock sensor data for tuning purposes.

 

Can something like that be done easily? Or am I looking at putting more crap under the dash?
