125 shot tune issue

[burtreynolds]

So I am running a custom tune, and I am about to throw a 125 shot on this motor. I am wanting to know what you all have removed timing-wise when you are running bottle (I was thinking 2 degrees). Also when you adjust the user specs on the SCT, does it knock back the timing from the stock setting or the advanced setting of the custom tune? Thanks for the help!

It removes timing from the tune that you have loaded or are going to load. A 125 shot I would remove 4* of timing. Now if you normally run your hot tune on 93 octane and wanted to run with the N2O you could put some c16 in the tank and leave the timing alone.

So lets say this hypothetical NA tune is 4 degrees advanced past stock when loaded. I on the user options drop the timing 3 degrees, thats still 1 degree past stock? Or is this -3 degrees from stock?

Yup +1 over stock. Do you know what the total spark is on the race tune? And what fuel are you going to use?

[burtreynolds]

Mix of race gas and 93 probably 112 oct sunoco. I dont know the advance on Zacks tune unfortunately but thats what I am running.

I would take 3 or 4 degrees out. You won't give up that much HP.
