Default why does power just fall off after spraying to 3rd?
I was trying out the new kit and I sprayed a 75 shot from first to the middle of 3rd and then at 5800 rpm's the car just took a nose dive. WOuld the air filter maybe not be flowing enough air or is it doing something crazy with the mass air? this is a dry kit.

No, you spray a dry kit before the MAF.

How's your fuel system, ie: injector size and fuel pump? I have had this problem before and it was just running out of fuel. Is it really falling on it's face big time?

I have a walbro 255 with 30lb svo injectors.
That should support well over my 420 rwhp and a 75 shot. I am going to change the fuel filter again and the spark plugs are tr6's but I have had them in since Last december . I will change them and see.

I vote for fuel starvation also. As I found out this weekend, you still need fuel for the Niutrous to work.

I agree your fuel system is up to the task if working properly. Have you checked the FPSS if you have one, as they sometimes are not adjusted correctly and can cause problems.

Can you see the O2 sensor voltages and any knock
retard when this goes on? That would do a lot to
narrow down the cause.
