I am curious from those that have dynoed a Gen 2 L while running an NX nitrous kit did your air/fuel ratio get richer or leaner while on the spray? NX told me that there kits are set up so that you should actually run a tad richer than you would off the bottle. Just wondering if anyone has any info on this?

 

i would think a wet kit and a tuned chip would add fuel to match your shot amount and then the nitrous would lean it back towards normal?

or maybe it just runs a tad richer since you're both adding fuel and pulling timing

 

I dynoed mine and had a richer tune. 11.1 to 11.3 across the entire run. I actually had to lean it out a tad to optimize.

 

is that AF with the nitrous?

 

Yup...on a VERY conservative tune. It got me 472rwhp and a whopping 720rwtq. No timing adjustments or added fuel.
