Well said thanks for the info

can some please help me why my fueling is all over the place and my fuel trims are wacky
no matter how much i change ve my afr jumps around whenever

running a literal straight pipe no muffler ...

yeh i see that too i had someone edit my file,

but thanks for the help, very much appreciated

but i got another question after i blip the throttle and let go, it gets way lean

its always happend on both sd and maf

Yeh its way better

I?m using the original tube that came off the car with a short cai

nah when i attach the files nothing happens

i tried jpeg and png

WOT why isn't my AFR changing
could it be my sensor it self

or maf ?

wont let me send picures so you have to copy and paste the link in google

i also ride with the hood off if that makes a differnce

why is iat so high its only 79 where im at rn
could it be my maf?

yeh def better

like at around 4:42 To 4:44 time in the log, the afr shoots way up to 20 when i let off the pedal.

and at points my bank1 shows significantly higher than bank2 so im leaning towards exhaust...

dont mind ect i was low on coolant
i it filled it up after

I will send a log later

I?m leaning toward exhaust leak because I welded my exhaust and I?m not really good at welding yet
So there may be holes near the o2 sensor

Yes
