I am also running e85 and nitrous now, have been working with Lund I get the tune down but it keeps going lean just on the hit and pulling timing. Doesn't matter what jets I have it seems either
Are you using a progressive controller? Mine still spiked a bit @ 50% nitrous starting at 3200. I'm moving the curve to the right and starting it at 12.5% and having it ramp in a little smoother.
I actually prefer a nice progression as traction is preserved and it just feels like a strong NA pull.
I also have a very well setup system and the hit, even at 50% is pretty hard. I think moving the fuel solenoid closer to the plate or using a Maximizer 4 to control the solenoid curves independently is key. I have a Max 4 and will probably try the independent control when I swap intake manifolds as I need to redo part of the harness for it to work.
