Jetting ?????

[John_Heard]

What jet sizes you got to play with? What pressure was it set at when you made that last run?

From .100 down and 5.5 6 psi fuel bottle at or near 1000 psi

Ok, according to Koehler's Nitrous Master Program you were at 5.23 N/F Ratio (5.5 psi) with 88/88 jets. Next step leaner would probably be an 88N/84F at 5.5 psi which would give you 5.74 N/F ratio. If it's still fat, then 88N/82F at 5.5 which would be 6.03 N/F ratio - which should start getting lean there, you should look at the plug strap and see where your timing is too. 8 degrees is a good place to start, but it might want a little more or a little less. If you put some more timing in it, it is usually a good idea to add some fuel too at the same time because that's going to put some heat in it - especially when you're getting close on the tune up.

Yeah Ill do that tomorrow .Did you build you truck or buy it? The reason I ask is there used to be one running around in Mobile Alabama that was just like yours.

Mine was built locally and also spent some time in Baton Rouge, LA.

What do you think about going to say a 92 or 94 no2 ?

Don't want to sound like a chicken turd, but I would tune what you've got before going to the next step. What I mean is, I would change the fuel jet to a smaller size and make sure all is well before I would go up on the nitrous jet. But, I guess everybody has got their own way.

Thanks Im going to bring a few jets with me and sneak up on the tune .Wish me luck
