Just bought an Autocal! Pretty excited. Hope the blackbear tune is as good as advertised! Seems like you cant go wrong with them. Pretty excited to see what they can do with my 8.1L and how much it opens it all up! Ill update as it all goes down

I bought the one off swap and sell today. I am waiting to get my new license. I have the 1500HD 6.0L I am excited to see what it does after a tune too.

All i can say is dont be expecting SO much... some guys are easily disapointed when they dont see a 150+ HP increase... you have to understand alot of the tuning is gettings things cleaned up and operating precisly and more effeicient!

The first in person tune i did with justin from black bear was an 04 8.1 yukon 2500.. and he got into it and was surprised at what he saw...so he made his corrections and adjustments and we drove the truck felt immeidiatly 10 times better just from the cleaning up.. These motors are pumped out on an assembly line "duh" so theres no fine tuning whatsoever... "example" why a 3.0 liter porsche makes twice the HP the a 6.0 or 8.1 chevy!!

You will be very happy with it..especially when you see the 2-4 mpg increase like i saw... Just try to remember your not bolting on a turbo or charger, and your keeping you warrany and safety!

Well i finally got my tune installed this morning. Took it for a quick spin. Can feel a bit of a difference in the shift points in the tranny. As for the engine, so far i dont feel a big difference but it does seem a bit quicker. Im sure i need to give it a few days to re learn everything. ill keep everyone posted on how it goes.

I did notice when i start the vehicle, it starts revs real high really fast then drops to idle. Kinda funky. Ill give it a few days and get back here.
