ok the car is getting boosted hopefully next week, only 5 lbs because its the stock motor. i know i can run more, but i would prefer not to. anyway, what settings in megatune do i need to change to go from N/A to turbo? is there anything aside from making sure my fuel and spark tables are set correctly? also, what kind of a/f should i bee looking for with boost?

Nothing will change except for your fuel and spark maps above 101 kpa. You should set your target AFRs in boost between 12.0 and 12.5 to be safe. Spark tuning is alittle bit tougher, you need to really listen to your car for any detonation and read your plugs.

Like kevin said, 12-12.5 AFR should be fine. You have to consider that 93 octane in Colorado isn't the same as 93 octane in Michigan, so you may have run a little richer. Remember that the AFR is a variable that is totally reliant on every other variable. In other words, you can't run a 12:1 AFR, with 25 degrees of timeing, on 93 octane, at 5PSI, at 4000 RPM and not expect detonation.

You also have to increase your AE.

I came across a thread that may help you, in relation to your AFR question. Read what Hex wrote in the below link. He gives an explanation to the unelaborate example I gave above.
