Default Am I getting a 300 shot?

My car ran 10.80@127 on motor.On the next pass I hit with a 300 shot.Went 9.7@141.I have a Nos mini progressive controller.I had it set at 99% which is its highest setting.I also have a timing tuner pulling 12 degrees of timing.My cars race weight is 3500.I have a powerglide,3.73 gears and 28" slicks.I have run the car many times with the same results.My nitrous setup is a direct port with a decaded fuel system.I'm getting 10.8 to 11.0 afr.I have gone down two jet sizes on the fuel.It was 10.0.
thanks

The air fuel is way to RICH....

Get the airfuel about 11.8. Until then you will not see the performance you are looking for.

Did you spray it on the dyno to see what kind of gains you were getting on the bottle? Nice times though.

it needs to be leaned out a little for sure. i wouldn't worry about the jets, just lower the fuel press on the dedicated system.

how do you like the glide in a "heavy" car?

31 jets on the nitrous
22 jets on the fuel
9 psi on the stand alone
Bottle pressure is between 1000-1100
Race gas in the cell and 3 step colder plugs
no dyno runs on spray
It seems like its only using 2 pounds of nitrous per pass.
love the glide.
I was wondering if I am pulling to much timing?Also wondering if the mini controller can handle the 4 solenoids?

dayum when i get the 9" in my car its going to get weighed and then i'll further make up my mind. just seems like it would be a dog out of the hole without a hella rear gear ratio. when you switched did you pickup any et/mph?

Damn... I am only picking up 12-14mph from a 200 shot. How fast are you running? I've attributed my "low" gain to a taller tire and lots more wind resistance due to speed. I am going 124-125 on motor and 136-138 on bottle. I spin a lot of the track, though, so I might be losing mph on that. I am only seeing 105 in the 1/8th.
