Whats it read while driving? Cause mine started doing the same thing after getting a flex pipe put in

driving im around 14 were it should be i have no fuel mods and just running the normal 17psi stage 1 i have a new exhaust coming so ill see if its the dp

I'm confused on what you think is the major problem

[LVOBSRT]

at idle im 17.9

[RedSRT4Me]

for how long?? Just for a second or when you start the car it idles at 17.9??

[LVOBSRT]

i start it up, let it do its thing, starts at about 14.5 or so then goes to 15.3 or so then down to 14.1 then shoots to 17s untill i hit the gas but when comming back to a idle it will go back to 17s

I know you said you checked for exhaust leaks already but it does seem like you still have one. What about when you are WOT? Is it reading correctly then?

[LVOBSRT]

yeah under boost im in 14 high 13 wot its 12 11 or 10im not sure but its were its supposed to be, i have a new exhaust on the way

I have the same problem. At a stop sign, or whenever it's idiling it'll max hte gauge out, and I'll get 3 dashes where the numbers are supposed to be. I can tell you that the dump tube on my AGP 50 trim is cracked badly where it comes off the WG. But I don't see how that would affect the afr's cause ti isn't routed back into the exhaust. I tried raising the fuel pressure up, but it never moves until I give it gas. It is also MUCH leaner under WOT, even before the boost really kicks in. thanks

before i put 100 octane in i had the same problem i would max it out at idle then when i put it in i now just play with 17.1-.9

[blew x u]

Fuel pump?

[LVOBSRT]

no i think its the exhaust i was looking at the dp from exhaust depot and its a 2 and a half head to a three inch exhaust thats bs i have a 3 inch o2 with flows thru that and its creating holes in the welding exhaust depots getting a email

[beyondspexj]

any word??

[LVOBSRT]

well i didnt want that guys exhaust, im not one to just have a straight pipe then tap into the pipe nd make dual then the other pipe becomes a fake. but imma take my stock dp and put a bong before the cat and see where im at
