2006 GTO running 93 pump with a 40N/30F at 900 psi bottle pressure through a 90mm NOS plate. Engine is a 370 forged LS2 and a P1 running 8lbs of boost. The heat on the plug looks good but the fuel is non-existant even though the wideband shows a .6 second lean spike up to 14 AFR and then the AFR ramps from 12.5 to 10.5 at the end of the run. What do you guys think? Is the run not long enough to see the fuel or am I just running lean? The fact that a 40 pill is adding 110HP/175TQ is also confusing but it makes the required 30F (50 psi fuel pressure) pill seem correct. Thoughts, comments? Sorry the pics are so small, they show up fine in the Streetfire album...

The nitrous gain in hp is going to be good on the blower. We have seen 200 hp shots pick up nearly 400 hp.

How long was the pull??

Was it on the dyno or was it on the street/track??

What system do you have?? Plate, nozzle, ??

What is your fuel system??

This was a 4th gear dyno pull using a 90mm plate and a return style fuel system with dual bro's. I could definitely see on a hot day with the charger spinning that the HP increase would be huge due to the cooling effect.
