Hitting the dyno soon..

[firebirdvert305]

Hey guys im gonna be hitting the dyno very soon with my current setup. But before that since im tuning with eprom chip and SAFC....i need some advice from the experts. The car will be on pump gas 93 octane for all runs. Current mod list is as follows: Evo 3 16g, 272/272 cams, FMIC, 3" exhaust, FIC 650 injectors, 2G mas, walbro 190 pump. Before I hit the dyno i need to get a custom chip made and im looking for any recommendations you guys can give me. I want to be running 20-22psi range, with the chip being programmed....im curious to know what kind of timing advance would you guys recommend to be put on the chip? Do you think id be able to get 18 degrees timing with very minimal knock and fairly low IDC's? Secondly I also want a custom eprom chip for 110 octane which I have never tuned before. What kind of AFR's should i be looking for on 110, as well as timing advance? Last but not least what kinda power should I expect to see on the dyno on pump and on 110? Any help would be appreciated.

Keydiver has chips already for pump gas timming, just email and ask.

I just put my new one in last Sunday, been running and tuning all week.

works very well, Im seening no knock at all up to 24 psi and im on 91 oct.

18 degree's sounds like a pretty good number, I definitly wouldn't try for more than that with that boost level and pump gas.

As for the 110 you could try something up in the 11.8-12.0 range and 21ish degree's of timing.
