My tune settings?
I was wondering if anyone has needle settings like this? .12tz 3port engine, P6 glowplug, 30% Byron race fuel. Settings are LSN 1/4 turn out, HSN 3/4 turn out. Idle stop screw at 1mm. The engine has lots of power and speed and runs at 210 degrees. Plenty of smoke out the exhaust at full throttle and some(very little) raw fuel out the exhaust at an idle. It also has a good idle.

the problem with mods on motors it that it narrows your tunning band and a speed is already modded from the factory, so I bet a modded speed is a handful to tune. I know with our speeds it's 1/4 hour increments once you get your tune close.

For me 3 1/2 turns out on the LSN would be super rich. Almost a break-in setting. That's where I start when I go back to a base setting and it always needs to be leaned in... A LOT. My settings are exactly 2 3/4 out on the LSN and 2 1/4 out on the HSN. Perfectly race tuned.

Needle settings depends on restricter size nitro % and pipe choose. I live in the south east and my vspecs speeds and ninjas all run around 3.5 out on the lsn and 2.25 on the hsn with mid needle flush at 9 oclock

Modded speed that's over kill, or any modded high end engines, I could see a cheaper b21bf 3-port, cuz I heard they become a new engine but a speed? What kind of differences did you notice?
