I started at 12.0 with 14* pulled out....
Traction is my issue...and I had an electrical issue...
so I stopped at at 12.5 for now....
will be going at it again once I swap everything into the mustang chassis
plugs look ok, but could definitely go a little leaner...
I'm on a #9 and may go to a #10 when I start to bring the timing back in..

I think the end tune up should be similar to what you guys are suggesting, once the OP has a feel for what he is doing and what this car actually needs.

I didnt say we didnt use plugs for timing, I said you cant do it accurately...meaning its not like you can tell if adding 1* was too much on the plugs....
plugs have a fudge room...sometimes, you add 2 and nothing changes
when if you had used a dyno for spark....you can actually see change in 1*
and typically your best judge of timing is not the plugs.. its your ****Edit*oops, sorry, meant to say MPH****....
when the car stops getting faster, you stop adding timing

I am not arguing that it will need to be in 12's most likely. I am saying that you should not just tell someone to tune it to the 12's on a wideband when they are clearly a novice to tuning.
Yes, all of those guys will tell you that. They are also very educated tuners who pull the plugs on nearly every pass. I tune the same way. But again, suggesting a novice to make a full afr point change based of a wideband is asking for trouble in my opinion.
Like I said mid-high 11's with the proper timing pulled out will not hurt anything. Of course there is power on the table, but that is not going to hurt parts. Make a pass with the same jets and a little more timing pulled out. Tune off of those plugs.
Small steps and going off of accurate plugs will keep the parts alive.
Ill skip the ABC paragraph on how tuning works. I just think your suggesting big changes to someone who needs to slow down.

Yep.
Yep.
None here as well. Everyone here has something more to learn.
Some are easier. E85 has a different way to read it than tradtional fuel's as does Alcohol.
