Need help! Don't laugh at me.. Question about timing

[fatride]

I going to purchase an Extender chip. But I would like some help in choosing the timing* When I do drive the car I will mostly be running 93 oct, + some zylene. Do I want to go with 18*??
I'm not sure if you guy's need to know some of my mods??
TE60, THDP, 50's, Alky, PTE Plenum, 3500 stall. I think thats good enough about the basics.
Thanks for the help in advance.

Will you be running the alcohol full time? If so, go with Bob's 23/21* chip. It has 23* in lower gears and 21* in higher gears.

Once I get my car dialed in I will be using the alky full time. I'm not experienced enough yet with the alky. So I will slowly get into using it full time.

If you have the translator + model with timing adjustments I'd prolly start with either a 20* chip or the alky. chip at 23/21 as previously mentioned.

I only have the Translator. No +
