    I have HPTuner Pro, so ya. I *think* something was up with the bottle contents at this point. There is just no other explanation... I'm tempted to put it back on the dyno with a fresh bottle from somewhere else... my last bottle contents smelled bad when vented...

    Yeah, I hear that, but the last two bottles I vented off didn't wreak this bad.

    maybe their supplier uses more ppm of sulphur....i dont see they can "cut" it when teh tanks are recieved under pressure...maybe they are switchin tanks or somethin'

    Maybe... but I watched the guy fill it last time and I didn't notice any funny biz going on.

    I could see 300lbft spikes too... (I got 163lbft on a shite bottle that only netted me 78HP... roughly half the expected gain) so double up my TQ numbers and I'm there with you.

    which weighs nothing. so, if the bottle is 10 lbs heavier after the fill, it's not air.

    You find FSANE'S TQ/HP ratio to be relatively normal?

    being an auto, then that accounts for most of the torque gain, due to multiplication from the converter. 100 rwhp gain on a 150 shot is low, but it depends on gearing and whether the nitrous is blowing through the converter.

    i did finally get 152 rwhp out of a 150 shot. let me find that graph.

    found it. i don't like this dyno i was using because it can never capture below about 3750 rpms for me. so torque numbers are lower due to that. this is NA vs 150 jetting
