i was giving some w.o.t runs on my truck today , from a 60 roll like 4 runs and all were at 10.8 11.0 a/f in 3rd gear so i stop and on my snow performance box i have it set to start 5 psi more or less and full was around 10-11psi, so i move the full to 19lbs so it wont turn on to full to c if i can lean it a lil and gave it another gas punch, my a/f was 9.9 all the way so i stop and check the box everything was how i moved it and gave it another run it felt sluggish and still 9.9 a/f, so i set the full back to where it was and still rich as hell , could it be something wrong with my meth kit all runs i was picking up the same amount of boost so it should not of richen out

 

the truck sat there for like 20-25 mins and went and tryed it again a/f was 10.7- 11.4
the stop ed for like 5 mins did another a/f was at 9.9 - 10.2 , and the 3rd run after that 10.7 - 11.3 why is my a/f going diff on difrent runs can it be high iats or something ?

im just getting so tired of this bull **** i myte just sell everything

 

What kind of tune? maf/speed density
Any way you can cut power to meth kit?

 

maf and yes my box is set for to shoot 10% only right now and it still dose diffrent in every pull

 

If you're blowing thru the MAF, it may be leaking. I've heard of MAF's blowing apart when blowing thru them. You may want to consider a speed density tune instead.

 

Yeah check that you havent busted your maf plastic housing. I understand that your meth box is only set at 10% but maybe its stuck some how internally? Try pulling the fuse to meth but becareful and watch afr's.Did your tuner scale down your air tables to avoid pegging the maf or did he adjust pe to compensate for air maf cant read?

 

but if its blowin tru the maf why dose it do an 11.0-11.4 a/f at first wen i step on it ? , can it be my fuel pressure regulator (the stock return type) that may be messing up ?

 

wouldnt it be rich all the time if my meth was messing up now that i come to think about it

 

i can cut power to the meth but im scared it may blow if i get too lean

today i gave it another punch and my friend said i had a ball of fire comming out my muffler , i even poured washer fluid by its self with no heet and still 9.9 on the second run

 

Ok you got me now. Your sure no more slip?
