ok I got a BDGT and I've downloaded a tune (regular gas, performance tune, removed WOT restriction). Definitely a difference in responsiveness. :eek_surprise: Wondering what difference people see with 'extreme' tune, premium gas? And how does one do the timing advance? Thanks in advance.

Find a mechanic with a newer snap-on scanner and they can advance your timing two degrees.

But can't the timing advance be done through the tuner itself?

I wish I could answer you! I never owned a BD product.

I have uprev in my truck after long-tube headers and replacing factory mid-pipe with cat-less mid-pipes and a complete cat-back.

Yes, you can do a two degree timing advance with the BDGT.

The 2* timing advance can be done through the BD. Make sure your up to operating temperature, otherwise it won't advance. If I recall properly, "extreme setting" was for the throttle response. A premium tune is just that and must utilize premium fuel.

Great timing for me on this topic.

I got a BDGT last month and have been playing with it looking for optimum setting.

In my desire to understand what is happening, I got a bluetooth OBDII reader and put the Torque app on my phone so I can log sensor data to see if I can figure out what is changing beyond seat of the pants sensors!

I haven't learned anything yet, but have a bunch of data..

When I ran the Extreme tune, the difference was incredible. I had the 2* advance on my timing also but found the throttle was too sensitive. The truck was twitchy. Fun as heck, but twitchy. Better without the 2* timing.

Now I am running "regular tune, WOT disabled, 2*, and speed limit at 151mph, but throttle sensitivity at stock. I'm gathering data and will compare to data collected when truck was stock (no DGT). The difference is subtle.

Then I'll change the tune settings and keep collecting data. I kinda doubt I'll figure it out but who knows..I like data and have the time.

My concern is that the tuner really only changes the throttle sensitivity and as such, creates the illusion of more horsepower.

If anyone has any insight into differences between tunes chime in. I'd love to know more about what this thing is doing.

Back in the day the most used tune was the Bully Dog Mid-Grade plus 2*.

I just put headers on so now I switched to UpRev.

 

[Bulkhead]

Why do you suppose that is? Was that configuration the best for blending performance with economy or did you guys find the best performance with that tune?

I have been running only premium fuel in my vehicle for years because I feel I get slightly better performance out of it so I am willing to continue to do so if the premium tune also results in better performance.

 

[Nick741]

If I remember correctly the guys that were going to the track all the time did better with that one than the premium tune.

Oh man the first message in that thread is from 9 years ago! LOL

Thx!

I did say "back in the day" on my earlier post. LOL
