So i just did a custom u-bend delete, and resonator delete. also i did a custom tune using a zzp platform. now i noticed that my exhaust smells like im running rich. also when i rev my engine while in park, until the limiter kicks in, as soon as i let off the gas a small plume of smoke comes out. it doesnt smoke while driving or while the engine is running at idle. im pretty sure im running rich. can someone give me some advice. as far as what can i do to fix this minor issue
 


yea i kno numbers dont lie, i just cant get a hold of my buddy with the hp tuner til saturday. if its a tuning problem i can find out then, but i was hopin somebody could give me some ideas of what some possible mechanical problems could be....
 
Why in the hell are you revving to redline while you are parked any ways? Good way to screw up your motor bro
 


with the limiter set at 4k is a different story, but still, rev the **** out of it with no load (parked) and scan it while doing so and watch your knock go ape **** speaking on general terms.

You have no clue what you are talking about.

I would say that this is fairly normal stuff, and assuming you did not disturb the upstream O2 sensor, you should not be having any issues.
 
The things you changed wouldnt cause you to run rich but the tune could so I would say thats your best chance
