Black bear tunes

First off the truck isnt a tahoe or yukon. Its a NNBS silverado with the same motor and all that. 5.3 vortec. I wanna know if they can tune out the 4 cylinder mode, get better mpgs and take off the governor at 98mph.

Yes and yes. Your best bet is to email them and they can give you all the info you need.

Then i need this. the 4 cylinder mode just annoys me. The truck will fall on its face cause it tries to drop into 4 cylinder right when i wanna take off

Just shoot JennaBear a PM and she'll get you set in the right direction.

I got my Burban Blackbear tuned back in 2010. He removed the top speed limiter, adjusted my speedometer to be correct for the non factory size tires I have, and adjusted the shift points in the transmission, and he turned on the pins in my ECM to add Efans.
I honestly have to say, the tune was by far the best money spent modding my truck.

I've read so many good things about this tune that I need to get off my ass and get it done already

will this tune void factory warranty?

So long as you return to stock, no issues. However, Magnusen Moss Act also protects you.
