Sounds Rich to me. My last setup was like yours and love it. Last 3 love it too. My setup now is 100% meth and two big nozzle.

I have to big nozzles on my kit also. We took fuel out added timing just did not like it.

What did you have the alky control settings at? Were you spraying 100% meth or a water mix?

Not sure what setting were. Washer 50/50

It's more than likely flooding it in. Gain knob on the dash should be half way. Inside the controller under the cover are 2 dials, adjust them so it turns on at say 5 psi and start the ramp rate out slow and go from there.

Water doesn't burn, I have good results on 100% meth.

Here's a handy lambda chart.

Maybe setting were not set right on the kit never checked. What did you guys gain with 100% meth over just pump power wise.

My kit start at 5lb and full spray at 15lb. running meth is like running 70% race gas all the time. This is a good guest on my part.

On just pump gas I made a little more peak horsepower but with the meth going I made a lot more average horsepower. We didn't spend a whole lot of time because I hadn't changed much since the last dyno tune, about 4 pulls. I walked away with 552.7rwhp and 575tq with an average rwhp of 403 from 2000 to 5800 rpm.

Checked on kit and nothing was setup on it. So when we used it on dyno must have been dumping to much without the settings made on it. So that sucks. Anyway we got the Autotrac TC swapped out put in AWD TC and front driveshaft back in. Put on a ground strap from alt bracket to block. Had problems with ground since bracket was powdercoated.


Got to block off the recirculate port on crossover of wastegate. Install DJM end links on rear swaybar. Get trans tune file back from Circle-D and do road tune.
