I pulled a P0300 code when I had low bottle pressure. It would run rough, and felt it felt like it wasn't making much power. I have a bottle heater now, and I haven't got that code since. Are you sure you are detonating? I detonated one time and I could hear it knock when I sprayed in 2nd gear at 2500 rpm, it sounded like a diesel. It spun bad in first, and I let off the throttle, when I got back into it, it had already shifted into second gear, the rpms dropped to 2500 and when I sprayed, it knocked bad. Haven't done that since.
I have a bottle heater and the pressure was about 1100 psi. I didn't hear a sprak knock sound, but it did set the code as a hard fault.

Do you know how much timing you have when you are spraying? I'm at stock timing which is around 20-22 degrees. When I tried to advance my timing more than 3 degrees with the Timing Tuner, I got that 0300 code.

I'm not sure what it is as, but I did pull about 3 degrees on the low octane table and 1 on the high.

wet kit or dry kit? its rule of thumb. 2-3 degrees for every 50 shot...a dry shot wont effect your NA tune. you can run 28* NA then have it set up for 22* for N20 all on same tune with nothing more then the computer doing the work

has anyone found a pump that isn't so susceptible to burning up when running the tank low?

For me I could care less about the $100 price what I care about is the fact that I will have to always closely monitor my fuel level so It doesn't go below 1/4 tank so I don't burn out the pump ( which I am horrible at keeping an eye on it) that is the biggest reason for me not to want to change it out.

So you think it is possible that I just don't have enough timing out? Im going to do a run and data log it tonight to find out where my timing is on the jug.
You say it needs to be about 22-23 right? Thanks for all the help by the way.

thats a general statment for the timing. i did a dry shot camaro other day with a 125 shot and i had his timing set at 22* but each vehicle might act differently
