got the analog gauhe from autozone...guess what.. reading -19 on idle. and +7 blipping the throttle haha

 

lol...trying fight off the smiles.

 

Cold start this morning

cool to see another sample. My idle fluctuates. Today was below -17 but I've seen it as high as -23

 

so what version of the exhaust did you get or did I miss it?

 

My first aem boost gauge was broke and I had to wait a week for a replacement

 

And presently. The connection on the back is janky. I have to fiddled with it to get it to read, then it works fine

 

Who is running a Stage two with the TRD Dual cat backs? (Is there anyone I should ask) or something similar/stock,,, other than the stage 2 stuff. I have lost track this last month or so? lost of goings ons!

 

I found a dirty deeds straight pipe locally for literally nothing. But I’ll probably add some resonators here soon when I get the O2 bung installed. But it does sound wicked lol

 

me

80mm harrop
Trd cat backs

 

Same. Definitely love it.

 

Same. I was seeing almost 11psi before cats blew out.. now with opened exhaust I'm at ~9.5 psi. Might have to put the 75mm pulley on once exhaust is done

 

^ do you have an idea as to why the cat problem occurred??

 

Surprised it is a straight pipe but video audio on YT has loudness normalization so it is hard to tell. Passed the wife which is more important.

 

After my last my last tune, at Peitz, Alex told me to keep an eye on the cats. they don't like the rich mix we have to give these motors.

mine have since not shown any visible symptoms....but I don't drive like a lot of you heathens.

 

Richness for sure. But I don't know of anyone else on here tuned by PS *with cats* except for me. Their R&D says you should run pig rich to keep the cylinders cool. I only had ~800 miles on my build before they blew out.

 

Rich on these motors is WAY better than lean for sure but with cooler plugs?? never mind?? I was just curios because you are the first to mention this? At some point though I would imagine that rich isn’t good neither?

 

As far as I know, running rich will only burn more fuel and potentially foul plugs prematurely? I'm the first on this forum to mention it, I believe. Facebook group has a few

 

I was running rich for a bit until she got tuned. cleaned the sensors and everything too. they were all black and i was driving the truck easy.
now im trying to determine whats causing my rpms to go up and down on Idle, or Drive but with brakes on. 50-200rpm difeerence. this happens when the engine has reached
operating temps. this has been happening since i got the SC. but I wasnt concerned until after the dyno becuase i thought it was just a bad tune.

 

That can be tuned out and adjusted

 

another weird thing. it doesnt happen 100% of the time. i say maybe 75%. and when she idles correctly, its solid and im right at 14.7 afr

 

I think I’ve seen people report issues due to the O2 sensor placement with LTH. Not sure what the fix for it is though. I thought Prospeed would relocate them to an individual runner on each side or something.

 

oh that's interesting. no wonder someone with the same exact setup as me was asking where my O2s where located...i responded with, before the cat. i think he was trying to ask regarding this topic. he is having the same issue as well. same truck, same mods, same issue...so maybe Stainless works lth?

 

See the comments on this post for more details. Sounds like it’s also a problem with ARH headers.

 

oh im in this group! thanks man!

 

This is correct. Waiting on a response back from Prospeed this week to tell me where and which collector to put the o2's on the Kooks. Only info I have now is, "up close to the cylinder head" There's an oscillation that occurs otherwise.

 

David from prospeed responded to my post in fb about my issue. they said about 3-5 inches away from the head flange

 

Was actually just reading that lol. Thanks for the info!

 

haha perfect!!

 

That sounds like a fun place to weld it in lol
