What is your air fuel ratio on Your turbo nytro

[juwalantz]

Just wanted to ask around and see what air fuel ratio nytro riders were at when WOT. I'm running about 12.5 I would like to lean it out just a little more. Just want to see what anyone thought. I don't want to lean it out if it is going to cause me trouble

Running 11.8 at sea level on mcx 190 pump gas. If your at 12.5 I wouldn't lean it out any more. Why tease the angry dog.

You will not want to run any leaner at WOT. You will find the explanations in the 2 links I posted for you.

Some info of your sled would be required to be able to help you out, but as AnythingButLast say, read and you will learn all you need to know.
For an very low boost setup 12.5 isn't to bad, wouldn't go leaner tho especially if compression isn't lowered, for an high boost setup 12.5 is to lean.

Here's what I do:

AFR's at
Idle: 14.0-14.7
Engagement: 13.5
0 lbs boost: 13.0
5 lbs boost: 12.5
10 lbs and over: 11.8-12.0

Cruise AFR's may be as high as 14 even With boost at light throttle and load on the motor.
