Ok i have had my meth kit set to come on 7psi and to be full by 10.5psi. Now i drove to the track on friday which is 2 hours away and i didnt really get on it to much on the way up there. I use about a gallon of meth that seems to much when should i start spaying like 9 or 10 and be full by like 11or 12 what does everyone else have theirs set to

 

10 psi on is a good number imho. But how you u know when it comes on? If you are using a controller, you should calibrate it. If you are using a boost switch you may be guessing...if you are using a tank of meth in a 2 hour street drive you are either on it a lot, or the calibration is off....imho

 

I have a switch that came with mine I have it set at 6psi but i'm sorta scepticale if it comes on right cuz my tank is barley empty and i had it for a while

 

i have the progressive devil own kit it uses the signal from the map sensor can it be calibrated and if it can how

 

Holy **** man, I don't think I've used a gallon total and I've had it on my car since august. And I'm not that easy on the car either. Thats including 7 passes down the track, and numerous pulls, kicking on at 8psi. Do you have a wideband to tell if its coming on early? It should get noticeably richer when it comes on.

 

i am tuned for it so idk if it willl get richer and i do have a wideband i went through about like 3/4 of a gallon in like 6 passes i am only using a 3gph nozzle

 

6 passes = say 6 x14 =84 seconds. with a 3 gal/ hr nozzle it says you have sumthin wrong somewhere. Infrared is more like it should be, i use a tank a month on the street...and i got a 7 g/hr nozzle

 

what could be wrong

 

A leak in your tank or lines probly. check it over maybe its coming on at 1psi or somthing.

 

i haven't check my lines yet but i don't think it i have a leak because i would smell it if it was in the car and it is not leaking at the pump and at the nozzle i think i just have it set to low so it is coming on alot more then i want it to

 

i would clean your check valve.

also, has your car been running like dirt at idle? is you supercharger cold enough to get your tounge stuck to it? if yes to either one of these then your checkvalve is sticking open. and you are siphoning the liquid out of the tank without the pump being on.

 

ok i will check the check valve but the kit has only been used for a week and i think it is richer at idle

i took the check valve out but how do i check it

ok i took it apart and there was something holding it open a little bit i hope that is what the problem was
