Prediction on dyno results are useless unless you can give some sort of detail as to which brand of dyno and the general operating conditions.

Even the same brand dyno can have anywhere up to 5% variation in reading if they're not calibrated right. Or 10-15 degrees difference during the day could easily result in 10hp difference in reading. You're looking at a potential variation of 20-30hp depending on dyno and condition.

I'd probably have better luck at predicting this week's lotto numbers than your dyno results.

Dyno numbers are pretty useless unless you have your stock numbers.

Definitely run map zero to see what your at stock and then you'll known your gains for the other two. Should be 60+.

just run any tuned map and than stock. if you run stock and than tuned you will get crappy numbers because of lack of adaptation.

Doing a run on map 0 is a good idea for a baseline. Then try to do at least 2 runs on each map with a 1-2 min cool down. Most around here like to see dynojet numbers.
