ChuckTaylors27 3 Posted 18 hours ago Has anybody had any issues with BlackBear Autocal that was not a user problem? Anything specifically pertaining to ECU lockup? I heard about that happening on an 8 speed dodge but was okay on the 6 speed dodge. From what I hear and what I read, blackbear is the way to go. Mostly what I am looking for is drivability and to tighten the hell out of my transmission as I just put a new one in. Other things id like to take care of is the Active Fuel Management, Torque Management System, and change up my stabilitrak/TC preferences. Im not so concerned with running e85 or premium tunes as what I can tell being stock it really won't make a huge difference in engine preservation. Does anybody have any experiences or knowledge to share for what I will see in the future choosing BlackBear, or maybe some suggestions to add to my list for Justin? Thanks guys

2014 GMC Sierra (5.3) is in for various upgrades, so the following items will be available in about a week. NO REASONABLE OFFER REFUSED! -stock exhaust headers -20" OEM chrome rims -stock step bars -stock calipers/rotors/brake lines (50k miles) -stock air intake -1 autocal with unused blackbear tune -1 diablo tuning device (I need to check if tune can be transferred} -Rancho adjustable lift shocks

I have a 2003 silverado 2500hd with the 6.0 (LQ4). It's been having a hard time starting for a few months and I have been able to avoid the problem by cycling the fuel pump with the key a few times. What happens is the engine will crank for a while and either not start on first attempt or will sputter to life slowly. Sometimes a second cranking cycle is required. Current list of mods and replacement parts include cold air intake intake/ flow master exhaust and Blackbear 91 tune. I have replaced the fuel filter with a high flow spin on filter and also replaced the fuel pressure regulator. I don't beleive it's a result of the tune because it had the issue every once and a while before the tune. (The tune is about 3 months old) My next step is either replace the fuel pump or injectors. Any help is greatly appreciated!

Has anyone had to claim anything warranty related to the power train while running a Black Bear tune? On my lists of things to do on my truck for this spring, is getting it tuned. I'm sick of how the transmission drives, and within the last month had to drive in a lot more traffic then normal. I just want to be confident that I can get at least 100k with the tune before something breaks.

Alright so after researching some options and getting some outside opinions on here, I'm pretty sure I am going to go with a custom tune from Black bear to get some more power and drivability. I do have a few questions though: 1. Is it possible to save multiple tunes with different settings? I love to have all the power I can just around town or messing around but also drive on the highway very frequently, so is it possible to have two (or more) separate tunes that I can easily switch back and forth between max HP and max MPG without having to replace the PCM? (Or is it possible to get a tune that maximizes both at once?) 2. What has typically been the total cost and how long does the entire process start to finish take when going with the scan cable tune? 3. Is it worth it to get an aftermarket air intake before getting the tune (wondering if a tune that optimizes the engine for greater airflow will yield better results?), or will the intake's effect still be pretty minimal? The truck is a 2006 Sierra Denali, 6.0L, AWD, 4.10 gears, around 135k miles. And I live in MT, so unfortunately it would be too long of a drive to get a tune in person anywhere that black bear goes.

I recently traded in my 2009 GMC Sierra 1500. I have an AutoCal from Blackbear Performance. It has never used or ever been out of the box. I would like to get $250 shipped for it. Please refer to this link to see what vehicles it will support: http://www.blackbearperformance.com/autocal.asp. Thanks for looking.

I have a EFILive AutoCal tuner for a 2010 Chevy Silverado 5.3. This tuner has never been used and has not been registered to a vehicle. This kit was purchased through Black Bear Performance. I am selling the kit due to selling the truck shortly after tuner purchase. I am looking to get $300. You can call or txt 315-529-9six2two for more information.
