Dynoed on motor, and 100 shot

I talked to a guy who did R&D at N.O.S. and he said that they found the best power and reliability with 11.6-11.8 or so on up to a 175 shot as far as A/F goes. He said that after the 175 mark things got kinda funky with tune needs.

N/A most aim for about 12.8-13.2

Also always remember to take out 2* of timing for every 50hp worth of n2o added or 1* for every 25hp added...so for ex. a 125 shot would need to be -5* from were the motor runs best N/A WITHOUT PING/DET. So if your at 14* off the bottle on your Dizzy then turn it back to 9 when your hitting that 125 shot.

A motor can make a little more power being on the slight lean condition but it depends on the motor and the setup. However I think you are over lean not slightly lean. You will have trouble if you don't get that taken care of. Richen it up and you should see even more power.
