So meth isn't flowing but it has flowed before though?

I'm thinking you need to reprime the system.

well..that could be a number of things. would need more info on your meth setup, what nozzle your running, is your pump function correctly, your meth mix ratio..could be boost leaks..could be anything really, are you saying your car is not pulling hard, misfiring, or is it just not putting down the power you used to have? it could be the fuel system..a clean fuel system makes a world of difference, ask me how i know also remember physics, awd pulls, rwd pushes, theoretically you should be pull on him.

I have a cm10 nozzle ..Meth is flowing 50/50 snow performece meth I no I should be pullin on him rigth no misfiring car rum good imjectors good coil spark plugs changed all new no boost leak i checked I had only o2 sensores cattles dp ...

#1 make sure your JB4 autotuning is off
#2 log boost and make sure you're getting what you are requesting (e.g. 18 psi peak to 15 at redline)
#3 vacuum leak off the DVs / DVs may not be fastened properly
#4 fuel system issue.

Get a log of your car (3rd starting around 3000 RPM to redline, shifting into part of 4th), post it up and we'll see what we can do to help you. You should pull an equally modded xi.

You don't need to go to a shop for this, just get someone to look at your system who's well versed in meth injection. Regardless you will need to do a datalog at the very least to see how the car's running.

[Bimmerfreakz]

Yea but just wanna see if there is anything else wrong with the car it's really werd that I spray meth with no pb. Ur no power

Assuming you have a JB4,you're really going to want to email Terry about these problems..he can point you to the right direction..

Or Shiv if you have a PROcede.

But as everyone said before, I'd check your solenoid, and lines for any leaks. If meth was flowing before, then the connectors in the JB4/PROcede should be fine. If you're not hitting target boost without meth, then you have a boost leak which could also be the problem. I'd start logging if I were you.

thanks guy for the help

[themyst]

Might want to check this.

Still think it's like chasing a ghost if you don't at least get one datalog.

I literally could not comprehend your question.
