This is a great example on the different ways to skin a cat when tuning a nitrous car and all are right. We all agree that its rich but you could either add nitrous (if you have the means) or take away fuel. The amount is gonna need to be decided by the user.

Another great and very safe point is, whenever making a system leaner(more heat) or adding nitrous(more heat) it is always safe to remove timing(heat) from the tuneup. You can always add timing back to get optimal results when you think the fuel is correct.

Good work boys

my impression is the engine was making good torque, but was lacking a little on top end power. ie, a little rich. Looks like at least another day of TNT, maybe more to get to the 300 shot.

NOW, the 800 lb gorilla in room is this:

I'm going to race at 4000ft, Top Gun Raceway, Fallon, NV. My regular track is 150ft AGL. I'm thinking Nitrous will not care one way or the other, since the same amount of o2 released in the combustion chamber under heat is the same. Am I on the right track here? We are going to tune my car N/A there before I run it.

up jet square means, once you have your tune up happy. And your a 42/26 like ours, you up both n/f the same amount. 44/28 46/30 and so on..

It's going to ask for more timing or nitrous with the elevation. Don't tune to hard up there. Wait till your back to your home track.

That works for a little moves, but it isnt technically the same ratio, so as you go up in Nitrous jets the spreads should widen.

Correct, it will also more than likely want less fuel as well

true, but i tend to let her fatten a tad when moving up. i can always lean her back out with a lil more N2O jet

Always different ways to do it. Either way will work well and safely for sure.
