Black Bear Tune


Recommended Posts

Posted

This will be my second BB tune.Justin is a great guy. Had one on my 06 and loved it. Really woke the truck up. I am in the process of getting a cable tune right now. I just sent him my log from a drive yesterday. Anyway my truck seems to idle a bit rough. Nothing annoying but you notice when you come to a stop. I was wondering if raising the idle 100 rpms would make any difference? It idle righ now around 550 which seems to be very low.

 

My other question is about the shifting. My last truck shifted pretty hard. Now with my 08 i kind of like the smooth shifting. You think its dumb to get tune and not get the shift pressures bumped up? I mean I know that makes the truck faster and thats what getting a tune is all about.

550 rpm does seem a little low.

Shifting preference is an individual preference.

I don't like HARD shifts, but I do like to FEEL/KNOW when it shifts.

I don't really like the kinda, "slipping from one gear to the other", on the new trucks.

I would prefer a SLIGHTLY firmer shift, but that is just ME and my preference. :dunno::crackup::crackup:

I had my BB tune at the Minnesota weekend, and Justin was really good in that respect. Especially for a guy like me who didn't really know what he wanted! :crackup:

 

I didn't understand what was meant when people say "cleaned up the shifting" but that's what he did. It shifts a little harder/firmer on normal driving, which I like. I almost wish I had him do more. But on WOT, it shifts HARD! :dunno: Again, that was set by Justin.

did you get a noticable power increase from the tune?

I did. I enjoy driving my truck a lot more after the tune. It's definitely a lot quicker off the line, which was my main goal. I was kinda hoping for black smoke on dry pavement, but that didn't quite happen. :dunno: I do have a crew cab, with the 5.3L engine :D

 

I want to put my factory ECM/TCM back in, just for fun. But throughout my process, I did that about 20 times, so I'm not real excited to do that any time soon. :D

 

Long story short, you'll like the tune :dunno:

Why so many swaps?

Hmmm, not real sure. I had some trouble when I put in the new ECM with my traction control and stabilitrac lights going off. Justin brought a new ECM to MN and that seemed to help it. I don't know if the ECM was bad, or if something happened when the program was uploaded. :dunno:

 

But I'm good at swapping them now! :crackup:

haha! Yeah, the swap on mine was easier than I expected.

 

I'm glad to hear it is all worked out now. :dunno:

Swapped mine out last night...I'm ready for this tune! I am also trying to figure out exactly what I want to have Justin tweak also. I saw a post a month or so ago by jennabear with questions to think about that Justin will ask us during the tune. Do any of you remember seeing that and know which thread it is in? i did a quick search but I didn't come up with anything.

I am not sure if that is for the GMT900s or the GMT800s, but I think it is the same
