What fuel octane should I be running? / What are you running ?

[Stangfreak95]

Mods in signature. I'm currently running 91octane and 14*timing. No pinging at all. Should I be running 94 ? Would I make more power ?

What is everybody using ?

Thanks

Running 93 with hell i dunno the degree timing. Just had it advanced until it didn't ping.

P.S. It's starting to ping. Time to break out the timing light.

running 93 octane and about 14 degree of timing... But I have to run 93 octane anyways

Those AFR's like a little more timing. Might want to try 16* or 18*, try a search on corral.

You'd really raise it to 16* ? How much octane for that then ?
I thought you did that, thought it ran better, went on the dyno and made your biggest gain on 10* ? Pretty sure it's you but could be wrong..

That's because I was using a tweecer which needs to be at the stock setting (10*). I adjusted the timing through the tweecer and it came out to a comparable 16*-18*.

I have my timing set at 10* but I got the EEC Tuner and I added 4* so I'm running 14*. To confirm, you then made your biggest power at 16*-18* ?
What gas are you running ?

Thanks Jake

I run 91 or 93, but I had to run 89 this past weekend because I was in BFE and there was no detination or loss of power. I would get on the dyno or go to test-n-tune because your butt can only feel so much, but it is cheap

Gotcha

93 Octane w/ 19* of timming locked w/ the Spout out.

You really want to run the least octane possible without pinging. You can play with the timing, and that will change things (more is not always better, BTW), but if you're running 91 now and don't change anything, 94 will not help -- may even slow you down.
