2g mas on 1g

[94Talon2]

I have a 2g mas I'm going to throw on my car. I've heard a 2g mas with 550cc work well together with hardly any tuning. How much tuning is needed, because I don't have an AFC. Does this set up need to be leaned? or richend? Who has this set-up without an AFC?

Thanks,

You should have the safc and a datalogger. I've done the 2g mas on a 1g vehicle many times and the results are never the same. On my brothers talon we had to lean it out a bit. On my cousins laser we had to richen it up a hair in the lower rpms. On my galant everything is at 0 for the low throttle settings on the safc. You could probably get away with it but it would be better to have the safc and a logger.
