with the water meth spraying at 5 and full at 12psi and no adjustments made to timing i get very little pull....my tests were done when the outside temps were 85-88 degrees pretty hot day... now most people i know with water meth have GIAC chip tunes....so this is what i think the difference is..apr becuz of their powerfull and smooth powerband has much different timing settings throughout the rpm range...only thing i can come up with...i get 2-3 pull in some cylinders...then when i just barely raised it to .75 advance (or one click up on channel 9 with unitune software) one time i got 10 degrees pull(only happened once) but on average it was around 5-7 in most cylinders.....car still runs great and def can tell when not spraying with stock timing(still apr tho) vs spraying like i said above at 5psi then full at 12psi now this needs to be thought on and APR wont help becuz they think im trying to steal thier program which is crap....but unitune DOESNT read the APR timing adjustments.... i asked APR how thier program works if the timing is set the same all the time or it changes depending on the RPMS and certain conditions they wouldnt say so if you have APR 93 oct and have water/meth let me know what you find out......email or post or even PM me

 

anyone? lol

 

On my friends S4 (APR stg3) we had to make the onset 12psi and full 17psi which was higher psi then recomended by a few people for the engines power/nozzle size I know there different engines but maybe turning your W/M settings to a higher psi will help you as well with his before we made that adjustment the car would not pull more then 5psi when it should have been making ~25

 

so the question here is that different programming works different/better with a w/m set up? Never heard of that before...it shouldn't matter what programming you have, I'm thinking.

 

the benefit of having it spraying sooner is that your cooling and controlling dentonation sooner in the rpm range and allowing you to have the power you want without issues....i dont have boost issues 20 psi all day long and steady

 

could of just been bad gas, try again with a fill up from somewhere else. There are many APR guys using w/m and adjusting timing w/ 0 issues
