250 shot hey guys i sprayed both stages of nitrous today while logging with hp tuners, my lc-1 read 10.9 to 11.5 thru the pull, i was in 4th gear when i got on it. when the first stage came on at 3000rpm (100shot) the tires broke loose, and then at 4500rpm (150shot) came in, felt real nice. when the first stage came in the lc-1 locked in around 11.9-12.2 and when the second stage came in the a/f dropped to 10.9 to 11.5.
does this sound like the A/F is right about where it needs to be? i am running 20degrees of timing to be safe as this was on 93 octain. i have 1/4 of a tank of gas now and i am gonna put some 110 in there tommorrow night for test and tune. i am shooting for at least mid 10's. one more question, looking at my log my engine temp went from 189 to 200 degrees and this was a pull from about 2500rpm to 5500rpm. are there any things i need to check before i run the car thru the 1/4 mile tommorrow. this will be the first run with both stages of nitrous. i plan on logging the runs.

pill sizes for the pill sizes on the first stage i have .032 on the dual nozzls so i assume its 100hp flywheel i figure 85rwhp with these jets. and i have the big shot nitrous noid on the second stage with the blue single nozzle pilled at .063 so i assume this would spray 150hp flywheel and 128rwhp. so i guess i will have an extra 210rwhp for the run. i will soon head to the dyno so i can jet the car to get a true 250 shot to the rear wheels. mods in the sig, fuel system is up to the task.

Pretty close on your hp rating. the a/f is good imo. On the LM1 Wb, if you don't use the correct % of smothing you'll get some real highs and lows, so I suspect that the lc1 uses no smothing and this can count for some of the peaks/valleys. I think your fine, a/f wise. If you are upping your octane you may be able to up your timing a bit, but logging for KR would be good, or do it on a dyno.
