Which Tune?

snowman44 · November 23, 2010

I have a 2008 GMC Sierra Denali with the 6.2L with a MBRP exhaust and K&N CAI. I have read some great things about a Blackbear tune but also have the option of bringing to a local performance shop who will put my tune on the dyno and tune the truck. I'm really having a hard time choosing. Justin has done many trucks like mine and know what and what does not work. Nut, I also like the idea of having the truck on a dyno and seeing real life numbers of what's working the best. I feel right now for a stock truck with 403hp this truck is a dog. I understand its not going to run like a corvette but just want it to get up and go a little quicker Any advice or input would be gretly appreciated.

I'd go for a Blackbear in person tune. It's what I did. I don't need to see numbers to know there is a difference. Street tuning and dyno are different. With the street things would be adjusted for the way you drive under different conditions. It would probably be better for shift points to be determined by real world driving. Justin has dyno information that you can look at for your engine. With Justin in your truck you'll be able to see, hear and feel what works best. Don't know what your local guy is charging and what kind of service he'll offer in the future, but BB tune tweaks are free for life. If you get the Autocal it will be simple to change tunes at your whim.

I asked this question when I joined the forums. You'll get alot of people say blackbear, its the transmission tweaks where you see the power from what I gather.

this is the kind of topic that should be stickied lol.

Dyno guy is going to charge me $450 with tune and runs on dyno. ANy idea how much it would be for me to meet with Justin in person and get tune with other module so I can change back to stock if I need to go todealer.
