Ok, NA I dynoed 415rwhp, but on the 180 shot I only gained 80hp. NX said they sent me the wrong jets (14's) , and I just received the correct jets (12's) today. At 10:1 that is rich, but I do not want to go too lean and pop my motor. But they "think" this is where the 100rwhp went.
what do you think? Could running to rich cause this much HP loss?

10:1 That is rich.

I ran 12:1 on my 150 shot.

10 to 1 is that with the 12's. I know the 14 were at that point the 12 should be in the high 11s. If it was the 12 I would increase the nitrous jet slowly.

MeanWS6

yes, that was with the 14's. NX said the size 12 jets will lean it out, but will I REALLY notice that much more power gain. I am just afraid to go too lean

to answer your queston, YES. the richer you run the motor the more power you will lose. also on the same note, if you run a motor too lean, you will also lose power. there is a window that you need to stay in to be safe and get the most power you can. i have heard of others having problems with that kit though so there might be something else to look at.

Still I cant imagine another 100 HP from decreasing the fuel jets. I'm sure jets sizing makes much more of a difference with the direct port setup though. Good luck.

You gotta remember too that a lot of the widebands only read down to 10.0 and then flatline and you may have been even richer.
