Who has black bear tune on 6.2??

[NORCAL SS]

Seeing who has a bb tune on their 6.2? I have a tune now and made 367/398 on 91 pump with a few mods but wouldn't mind trying bb tune to see the difference.

I know i see tons of 5.3 guys but trying to get feedback from 6.2 guys.

I have one on mine, it's just a 93 tune and to relieve the sloppy shift points ... I don't have any engine mods on my truck so I'm not sure how helpful I can be. But it made a huge difference for my needs and I'm very happy with it.

I went from 328 RWHP to 344 on a heartbreaker dyno with just a tune, otherwise bone stock. Adding an Airaid tube and K&N in the stock air box with BB tune for that added more, but I haven't been back to a dyno. I'm guessing now 350+ RWHP on Ca. 91 octane and no other mods.

I need to get Justin to revise the last tuning file but haven't got around to it. At one point he had the shifting just about right, but I "lost" the fix he gave me for a very early 2-3 shift when he sent the last tune for the tube and K&N. It really needs to have that shift delayed 100-150 RPM at part throttle. Stock, the shifting was way to soft. It's worth it.

Right on I have a few bolt ons now plus just put a ported manifold so hoping 409/415

My tune now only has 16 degrees of timing and vvt nit touched so I know has to be more there.

I am bone stock except for the tune and a cut resonator. If there is a 4wd dyno nearby that can support a Yukon I'd try.

4wd dyno's are tough to come by. You can't pull the front drive shaft unfortunately. Still trying to work out the details on a Magnuson. Any change in noise or power without the resonator? I'd like to lose it for the weight savings and looks, but don't want any more noise.

I cut my resonator off my 5.3 avalanche and there is definitely more noise. Hence why I didn't cut it off the escalade and just got a GM Accessory factory chrome tip add-on.

Got the BB tune for my blower. No dyno yet to show any numbers. Id love to see where it sits at now. Love the tune just takes forever dialing the trans right on when you deal with it via email.
