New Dyno with N20

In the sig. I ran a bit lean 13.5, NA was 12.2

What would be the best way to richen it up?
Switch to wet?

Good numbers.....I thought though that the ls1's came out with way more than 273rwhp though from the factory....I thought it was like 315 or something? I don't reall know because I've never owned one. My stock LT1 made 276.6wrhp when I got it but that was descreened and all of the free mods. And in your sig you have a nx wet kit but you have 100 dry shot beside it....are you using the wet kit because its a wet shot....Glad to see that you got all of your 100hp to the ground though....I only got about 80 to the wheels with the 100 shot...I think my bottle pressure was getting low though....I didn't have a gauge to check.

Thanks. A4's dyno a bit less than M6's. Which is usually around 300 rwhp. I was disappointed with mine.

Yes it is a wet kit. But right now I am using it as a dry. But since I am running a bit lean, might have to switch and go wet.

I dont know.. perhaps headers or a large fuel pump?

Headers would take me over the 400 mark. But changing jets is so much eaiser and cheaper. :)

Not sure a fuel pump would help on such a small shot. But it woudn't hurt.
