SCT adding timing to 91 tune

[wheelin]

Hey guys I have a 91 tune and I always run 94 octane and I'm at the race track Tommorow . I was told I could run 2 degrees more timing .In the SCT there are 0-2000 rpm 2000-4000 rpm and 4000+ areas to increase timing ,when I increase the timing should it be increased in all 3 sections?


Thx mike

The first option is "global". Use that instead of doing by rpm range.

In general, no. Boost and heat factor in heavily. If you're truly running 8-9psi and your temps are cool AND you're sure you have really good gas, sure. But as you can see... Lots of variables. If you're running a 93 street tune from a professional tuner, you're very likely running 16-18 degrees of total timing as it sits.

Cute. Like I said, LOTS of variables. And as a general rule, "no". But I think you perhaps underscored those thoughts.

there is nothing 'premium' about premium pump gas.
