Scuba78

lust installed the motofab 2" in the front. running all stock 18s. debating on a tire size. was thinking 285/65R18 but not sure. FHLH looks like mine, not sure if i should go any bigger

after exhausting every avenue with GM, BBP was the best to deal with and have addressed my issue. I was very confident from the start all these issues were programming flaws. After their tune the truck drives very smooth and is a lot more responsive. VERY VERY happy with the results. Such a shame GM would not back their own product.

It has been night and day with the truck. It drives so much better. I have now added a cat back exhaust and had it returned for that and removed AFM. The change from 8 to for always had a funny kick. It is now even smoother. Best thing I have done to the truck I actually enjoy driving it.

Mine Chirped bad, dealer replaced the entire exhaust with only 5k miles! i tried to get them to swap it for my choice, but no go.. I will do a mod soon. curious if anyone has tried just getting rid of the resonator.

Yes, i too had those issues but with Black Bear they changed the TCM as well and in my opinion it drives how i would drive a manual. it holds the gear it needs instead of the one it should be in on the highway!

I wish i bought an older truck, not new

i have had every TSB and update available. Noting from factory has helped, but i solved the issue myself, with help from Black Bear Performance!!! i sent them my read file and told them the issues im having, they sent me the tune last night ant this is the first day with the truck after 20k miles it didnt lug and chug at ALL! I will be going to my dealer to show them the results to just shake it in the engineers face. What good is a warranty if they wont do anything about it anyway!

2017, bought jan 28, 20,585...not quite a full year yet.

Drive to NH, i have the same truck and wish the Z71 had chrome

This has been very helpfull. I was debating wheels for my truck and i do like black wheels, but on silver, IMO, it doesnt look as nice. not trying to bag on anyone but for my taste i will go with silver or chrome. In defense, i had black wheels on my Green 04 diesel, and loved it! still miss that truck, bad!

Facts are facts sir.

I have a Short GF who is wanting me to get a set...not a fan of any either so...i guess i will pick one that looks good. Cheaper to get rid of the GF thou...

i know, i am one of 6 at this dealership with the same issue. almost 50K for a truck that drives like crap, sucks

No. it does it locked in V8 mode. Tech and i drove for an hour playing with all the functions. Bottom line, in V8 mode, torque Converter locked it feels like a fish biting on the line as you steady cruise or very light acceleration. comes down to Tune issue. not enough fuel. when I install the programmer we should be able to confirm it if it smooths out. I have been working with the dealer and the Tech for quite some time. I'm pretty competent with cars and the dealer knows my background. we have spent a lot of time trying to narrow this down, then the engineer says its normal...not too happy with them
