I just added plugs, wires, belt and idler pulley for my wifes Burb.

The next day I drove down to Chula Vista and met up with Justin for the Black Bear Tune.

He is a great guy and really took the time to make sure everything was running great and we got the most out of the tune.

Our Burb is an 09 6.0 2500 with almost 174,000 miles on it. It runs like its new.

I put a fuel pump in it because I travel cross country often and needed insurance lol.

New shocks installed at 145,000.

I am debating on the exhaust and intake but not sure the juice is worth the squeeze??

On a side note Justin suggested 89 octane as well…….so I have reluctantly took his advice (4.01 out here in Cali).

 

Awesome! Did the tune turn off the AFM system?

 

I didnt know the 3/4 ton burbs with the 6.0 had the AFM

 

They don't.

 

Yea, i mash the pedal on mine and i feel like i'm in a Muscle car, no AFM
in the 2500's

 

Yep…no AFM here. I really cannot believe how smooth the Burb runs after a tune up and the Blackbear tune. It had a little ping at idle but that went away and the extra pep from the tune is nice. I am excited to see what fuel numbers are on a long trip. I am debating on what to do next

Headers and exhaust seems like over kill for something I don't really drive but it sure sounds cool haha

 

lol! Sorry I didn't know either! I didn't even know you could get a 6.0L in the Suburban for the new body style years. Learned something new!

 

Thats okay, now i guess GM felt the need to do away with the 3/4 ton
Suburbans, oh well

 

What the heck......I'm gonna do the Duraburb conversion on it one day.
