Losing top end power So... I went back to the track Saturday, still using a 100 shot, and got a little bit better... but something it happening on the top.
I gained 2mph in the 1/8th but lost 0.5 in the 1/4... I'm guessing my injectors are maxed out (dry shot)... CEL came on for random misfire.
Any ideas?
A friend of mine said it could have been a big drop in bottle psi and there was not as much n2o but the HSW Interface was still adding fuel and I went rich?
So..it's either a rich or lean condition..haha

No, It is about half full.....not sure how much the PSI is...my ZEX bottle gauge is broken..hah
I've sprayed the 100 shot a few times before and it never had this happen. But this time I did leave the bottle heater on longer than I normally do...so maybe it actually had good PSI in it compared to the other times..
I know I really need to get a gauge though.

take the bottle out and weigh it. I try to keep my bottle over 18 lbs, anything under i seem to have problems keeping the pressure up. But its a little easier to keep em full when u can fill it at home. Oh yeah the bottle weighs around 14.7 empty

Edit: I see you're from Memphis, I don't think I've ever seen your car around.

Only thing changed was higher bottle pressure.
Surely if I picked up 2mph in the 1/8th it should have reflected that at the end, right?
Yes, I have a filter and bottle heater. I have a bad habit of not leaving the heater on long enough though...so this past track day I actually had it on. My guess is that is how the car gained 2mph in the 1/8th on the same size shot. But like I said...misfire light came on and I lost 0.5mph in the 1/4.

Dude, you live like half a mile from me. Give me a call on stuff like like!
I'm in Orlando right now, doing some training sessions with Wells and Bosch we set up. I'll fly back in Thursday evening. I have multiple gauges and whatnot. If you're free Thursday or Friday I'd gladly try and help you diagnose it. I just wanna watch bottle pressure and read the plugs.....let me know man

Thanks for the suggestions everyone!
Yeah, if you have a nitrous gauge I could buy that would be nice. BB&T only has ZEX ones and it broke on me so I don't want another one of those.
I plan on going racing this Saturday so hopefully we can figure out something
My car is very consistent on and off the bottle. The weather was really nice this past track day and I gained N/A and on the bottle. Launching and shifting was the same (I have an auto). I'll go check the filter now.

1.71 ---- 1.69
7.80 ---- 7.68
88.86 ---- 90.28
12.20 ---- 12.02
112.19 ---- 113.21
So..gained 2mph in the 1/8th N/A and on the juice.. 60ft times on the bottle were the same ...1.592 and 1.594.
1.59 ---- 1.59
7.27 ---- 7.15
95.78 ---- 97.09
11.37 ---- 11.23
118.83 ---- 118.53
The weather was a lot less humid on the better runs, but temperature was about the same.

Well, the bottle was definitely my problem..and now that I have a working nitrous gauge it makes things so easy.
Went to the track tonight...and it was very cold, the track was cold, and I couldn't hook up and still ran a 11.2!! With a bad 60ft! So the car definitely has some 11.1xs in it with my usual 60ft.. (maybe even a 11.0??????)
