5.3 Sierra Throwing Codes

[sarah_ima64]

I need help last weekend my Chevy suburban turn on light check engine I had this codes p0420 p0430.

I installed shorty headers with stock cats.

Can you help me to turn off o2 sensor ?

I can certainly get you hooked up with a custom tune for your truck and mods, and disable the necessary trouble codes and related items, etc etc...

How much is for custom tuning ?

[06MonteSS]

Which diablo tool do you have, the inTune or Trinity? What year is your suburban?

my custom tuning is only $135 USD...

Here's info about my custom tuning:

http://www.diablewtune.com/

there are links on there to the info you'll need - i.e. how to import/export the tune files I need from you, how to do a data log, what parameters to log, paypal "Order Now" button for purchasing the custom tuning, etc... as well as a link to just a small sample of just some of the "Testimonials" I've received from people I've done my tunes for - makes for good reading, hehe.

What I'd need from you is a copy of your "original backup" stock tune file, a copy of the "last tune written" tune file, a steady driving datalog, the paypal, and that's it... then we're good to go. and I can usually have the initial custom tune done and sent back to you within 24 - 48 hours from the time that I receive everything. You can find the info/instructions for logging and getting me the files, on my site www.diablewtune.com at #5 for the inTune.

you can email me directly: [email protected]

Thanks for asking man, I appreciate it!

I just got my Intune today and I installed the 87 tune and I'm having the same issues and I bought new O2 sensors and replaced them and still throws the P0131 and P0151 codes?? I put it back to the stock tune and it doesn't throw any codes?

It ended up being my mass airflow sensor. Runs great, considerably more power over stock and I get at least 1mpg better.
