How much timing do you place in a mail-in flash?

I am curious because I am thinking about spraying on top of one of your mail-in's.

Thanks.

 

More specific info would be needed....flashes are dependent upon mods, model, and fuel.

 

'03
GSC 272/272
Buschur TBE
MBC @ 21 psi
Walbro
Injen intake kit
APS BOV
93 octane

 

odds are they will pull about 16% of your fuel up top. This will have an affect on engine timing and advance it a few degrees. Ignition timing will more than likely be pulled 3 degrees. So basically most of your advance in timing will come from leaning out the AFR.

 

Al?

 

The timing varies with the mods and the fuel used - in 99% of cases its more than stock and smoother than stock
