I was thinking the other day, i havent gotten great, great mileage ever since I got my first tune. I got it mail order tuned before the cam and retuned after the cam.

When I start over with a stock tune, what do I need to change to get my cam to idle and run right? I went through VE tuning and got it within +-3 on the tune I have now, but never got any further.

 

All you really need to do is adjust the RAF table, and to smooth out the idle, just play with the idle spark table. You should be good.
